The design research presented here aims to develop a design methodology that can compute an architecture that participates within the new digital economy. As technology advances, the world needs to quickly adapt to each new advancement. Since the turn of the last century, technology has integrated itself within our everyday lives and deeply impacted the way in which we live. This relationship has been defined by TM Tsai et al. as “Online to Offline” or “O2O” for short. What O2O means is defining virtually while executing physically, such as platform-based companies like Uber, AirBnb, and Groupon do. O2O allows for impact or disruption of the physical world to be made within the digital world. This has significantly affected economies around the world.
Paul Mason outlined in Post Capitalism: A Guide to our Future (2015) that developments in technology and the rise of the internet have created a decline in capitalism, which is being replaced by a new socio-economic system called “Post Capitalism”. As Mason describes,“technologies we’ve created are not compatible with capitalism […] once capitalism can no longer adapt to technological change”. Traditional capitalism is being replaced by the digital economy, changing the way products are produced, sold and purchased. There is a new type of good which can be bought or sold: the digital product. Digital products can be copied, downloaded and moved an infinite number of times. Mason states that it is almost impossible to produce a digital product through a capitalist economy due to the nature of the digital product. An example he uses is a program or software that can be changed throughout time and copied with little to no cost. The original producer of the product cannot regain their cost as one can with a physical good, leading to traditional manufacturers losing income from digital products. With the increase in digital products, the economy must be adapted.
In The Second Digital Turn (2017) Mario Carpo describes this phenomenon, stating that digital technologies are creating a new economy where production and transactions are done entirely algorithmically, and as a result are no longer time-consuming, labour intensive or costly. This leads to an economy which is constantly changing and adapting to the current status of the context in which it is in. Carpo describes the benefits of the digital economy as the following: “[…] it would appear that digital tools may help us to recreate some degree of the organic, spontaneous adaptivity that allowed traditional societies to function, albeit messily by our standards, before the rise of modern task specialisation.”
It is useful to look at the work of Kurt Gödel and his theorems for mathematical logic, which are the basis for computational logic. In his first theorem the term “axioms” is presented, which are true statements that can be proven as true. The theorem states that “If axioms do not contradict each other and are ‘listable’ some statements are true but cannot be proved.” This means that any system based on mathematical statements, axioms, cannot prove everything unless additional axioms are added to the list. From this Gödel describes his second theorem, “A system of axioms cannot show its inconsistency.” To relate this to programming, axioms can be seen as similar to code, yet everything cannot be proven from a single system of code.
Allen Turing’s work on computable numbers is a result of these two theorems by Gödel. Turing was designing a rigorous notion of effective computability based on the “Turing Machine”. The Turing Machine was to process any given information based on a set of rules, or a programme the machine follows, provided by the user for a specified intention. The machine is fed with an infinitely long tape, divided into squares, which contains a sequence of information. The machine would “scan” a symbol, “read” the given rules, “write” an output symbol, and then move to the next symbol. As Turning described, the “read” process refers back to the rule set provided: the machine would look through the rules, find the scanned symbol, then proceed to follow the instructions of the scanned symbol. The machine then writes a new symbol and moves to a new location, repeating the process over and over until it is told to by the ruleset to halt or stop the procedure and deliver an output. Turing’s theories laid down the foundation for the idea of a programmable machine able to interpret given information based on a given programme.
When applying computational thinking to architecture, it becomes evident that a problem based in the physical requires a type of physical computation. By examining the work of John von Neumann in comparison with Lionel Sharples Penrose the difference between the idea of a physical computational machine and a traditional automata computation can be explored. In Arthur W. Burks’s essay ‘Von Neumann’s Self-Reproducing Automata’ (1969) he describes von Neumann’s idea of automata, or the way in which computers think and the logic to how they process data. Von Neumann developed simple computer automata that functioned on simple switches of “and”, “or”, and “not”, in order to explore how automata can be created that are similar to natural automata, like cells and a cellular nervous system, making the process highly organic and with it the ability to compute using physical elements and physical data. Von Neumann theorised of a kinetic computational machine that would contain more elements than the standard automata, functioning in a simulated environment. As Burks describes, the elements are “floating on the surface, […] moving back and forth in random motion, after the manner of molecules of a gas.” As Burks states, von Neumann utilised this for “the control, organisational, programming, and logical aspects of both man-made automata […] and natural systems.”
However this poses issues around difficulty of control, as the set of rules are simple but incomplete. To address this von Neumann experimented with the idea of cellular automata. Within cellular automata he constructs a series of grids that act as a framework for events to take place, or a finite list of states in which the cell can be. Each cell’s state has a relation to its neighbours. As states change in each cell, this affects the states of each cell’s neighbour. This form of automata constructs itself entirely on a gridded and highly strict logical system.
Von Neumann’s concept for kinetic computation was modelled on experiments done by Lionel Sharples Penrose in 1957. Penrose experimented with the intention of understanding how DNA and cells self-replicate. He built physical machines that connected using hooks, slots and notches. Once connected the machines would act as a single entity, moving together forming more connections and creating a larger whole. Penrose experimented with multiple types of designs for these machines. He began with creating a single shape from wood, with notches at both ends and an angled base, allowing the object to rock on each side. He placed these objects along a rail, and by moving the rail forwards and backwards the objects interacted, and, at certain moments, connected. He designed another object with two identical hooks facing in opposite directions on a hinge. As one object would move into another, the hook would move up and interlock with a notch in the other element. This also allowed for the objects to be separated. If three of these objects were joined, and a fourth interlocked at the end, the objects would split into two equal parts. This enabled Penrose to create a machine which would self-assemble, then when it was too large, it would divide, replicating the behaviours of cellular mitosis. These early physical computing machines would operate entirely on kinetic behaviour, encoding behaviours within the design of the machine itself, transmitting data physically.
Experimenting with Penrose: Physical Computation
The images included here are of design research into taking Penrose objects into a physics engine and testing them at a larger scale. By modifying the elements to work within multiple dimensions, certain patterns and groupings can be achieved which were not accessible to Penrose. Small changes to an element, as well as other elements in the field, affect each other in terms of how they connect and form different types of clusters.
In Figure X, there is a spiralling hook. Within the simulations the element can grow in size, occupying more area. It is also given a positive or negative rotation. The size of the growth represents larger architectural elements, and thus takes more of the given space within the field. This leads to a higher density of elements clustering. The rotation of the spin provides control over what particular elements will hook together. Positive and positive rotations will hook, as well as negative and negative ones, but opposite spins will repeal each other as they spin.
Through testing different scenarios, formations begin to emerge, continuously adapting as each object is moving. At a larger scale, how the elements will interact with each other can be planned for spatially. In larger simulations certain groupings can be combined together to create larger formations of elements connected through strings of hooked elements. This experimentation leads towards a new form of architecture referred to as “codividual architecture”, or a computable architectural space created using the interaction and continuous adaptation of spatial elements. The computation of space occurs when individual spaces fuse together, therefore becoming one new space indistinguishable from the original parts. This process continues, allowing codividual architecture of constant change and adaptability.
Codividual spaces can be further supported by utilising machine learning, which computes parts at the moment they fuse with other parts, the connection of spaces, the spaces that change, and how parts act as a single element once fused together. This leads to almost scaleless spatial types of infinite variations. Architectural elements move in a given field and through encoded functions – connect, move, change and fuse. In contrast to what von Neumann was proposing, where the elements move randomly similar to gaseous molecules, these elements can move and join based on an encoded set of rules.
Within this type of system that merges together principles of von Neumann’s automata with codividuality, traditional automata and state machines can be radically rethought by giving architectural elements the capacity for decision making by using machine learning. The elements follow a set of given instructions but also have additional knowledge allowing them to assess the environment in which they are placed. Early experiments, shown here in images of the thesis project COMATA, consisted of orthogonal elements that varied in scale, creating larger programmatic spaces that were designed to create overlaps, and interlock, with the movement of the element. The design allowed for the elements to create a higher density of clustering when they would interlock in comparison to a linear, end-to-end connection.
This approach offers a design methodology which takes into consideration not only the internal programme, structure and navigation of elements, but the environmental factors of where they are placed. Scale is undefined and unbounded: each part can be added to create new parts, with each new part created as the scale grows. Systems adapt to the contexts in they are placed, creating a continuous changing of space, allowing for an understanding of the digital economics of space in real time.

“…the rigour of the architecture is concealed beneath the cunning arrangement of the disordered violences…”
This essay investigates the potential of codividual sympoiesis as a mode of thinking overlapping ecological concepts with economics, contemporary philosophy, advanced research in computation and digital architecture. By extending Donna Haraway’s argument of “tentacular thinking” into architecture, it lays emphasis on a self-organising and sympoietic approach to architecture. Shifting focus from an object-oriented thinking to parts, it uses mereology, the study of part-hoods and compositions, as a methodology to understand a building as being composed of parts.
It argues the limits of autopoiesis as a system and conceptualises a new architectural computing system embracing spatial codividuality and sympoiesis as a necessity for an adaptive and networked existence through continued complex interactions among its components. It propagates codividual sympoiesis as a model for continuous discrete computation and automata, relevant in the present times of distributed and shared economies.
A notion of fusing parts is established to scale up the concept and to analyse the assemblages created over a steady sympoietic computational process, guided by mereology and the discrete model. It gives rise to new conceptions of space, with a multitude of situations offered by the system at any given instant. These sympoietic inter-relations between the parts can be used to steadily produce new relations and spatial knottings, going beyond the most limiting aspect of autopoiesis, enabling it to begin to produce similar patterns of relations.
This essay extends the conceptual idea of tentacular thinking, propagated by Donna Haraway, into architecture. Tentacular thinking, as Haraway explains, is an ecological concept which is a metaphorical explanation for a nonlinear, multiple, networked existence. It elaborates on a biological idea that “we are not singular beings, but limbs in a complex, multi-species network of entwined ways of existing.” Haraway, being an ecological thinker, leads this notion of tentacular thinking to the idea of poiesis, which means the process of growth or creation and brings into discussion several ecological organisational concepts based on self-organisation and collective organisation, namely autopoiesis and sympoiesis. It propagates the notion that architecture can evolve and change within itself, be more sympoietic rather than autopoietic, and more connected and intertwined.
With the advent of distributed and participatory technologies, tentacularity offers a completely new formal thinking, one in which there is a shift from the object and towards the autonomy of parts. This shift towards part-thinking leads to a problem about how a building can be understood not as a whole, but on the basis of the inter-relationships between its composing parts. It can be understood as a mereological shift from global compositions to part-hoods and fusions triggering compositions.
A departure from the more simplified whole-oriented thinking, tentacular thinking comes about as a new perspective, as an alternative to traditional ideologies and thinking processes. In the present economic and societal context, within a decentralised, autonomous and more transparent organisational framework, stakeholders function in a form that is akin to multiple players forming a cat’s cradle, a phenomenon which could be understood as being sympoietic. With increases in direct exchange, especially with the rise of blockchain and distributed platforms such as Airbnb, Uber, etc. in architecture, such participatory concepts push for new typologies and real estate models such as co-living and co-working spaces.
Fusion of Parts: Codividuality
In considering share-abilities and cooperative interactions between parts, the notions of a fusing part and a fused part emerge, giving rise to a multitude of possibilities spatially. Fusing parts fuse together to form a fused part which, at the same stage, behaves as another fusing part to perform more fusions with other fusing parts to form larger fused parts. The overlaps and the various assemblages of these parts gain relevance here, and this is what codividuality is all about.
As Haraway explains, it begins to matter “what relations relate relations.” Codividual comes about as a spatial condition that offers cooperative, co-living, co-working, co-existing living conditions. In the mereological sense, codividuality is about how fusing parts can combine to form a fused part, which in turn, can combine to form a larger fused part and so on. Conceptually, it can be understood that codividuality looks into an alternative method for the forming and fusing of spatial parts, thereby evolving a fusion of collectivist and individualist ideologies. It evolves as a form of architecture that is created from the interactions and fusion of different types of spaces to create a more connected and integrated environment. It offers the opportunity to develop new computing systems within architecture, allowing architectural systems to organise with automaton logic and behave as a sympoietic system. It calls for a rethinking of automata and computation.
Codividual can be perceived as a spatial condition allowing for spatial connectivities and, in the mereological sense, as a part composed of parts; a part and its parts. What is crucial is the nature of the organisation of these parts. An understanding of the meaning and history of the organisational concepts of autopoiesis and sympoiesis brings out this nature.
Autopoiesis: Towards Assemblages of Parts
The concept of autopoiesis stems from biology. A neologism introduced by Humberto Maturana and Francisco Varela in 1980, autopoiesis highlights the self-producing nature of living systems. Maturana and Varela defined an autopoietic system as one that “continuously generates and specifies its own organisation through its operation as a system of production of its own components.” A union of the Greek terms – autos, meaning “self” and, poiesis, meaning “organisation” – autopoiesis came about as an answer to questions cropping up in the biological sciences pertaining to the organisation of living organisms. Autopoiesis was an attempt to resolve the confusion between biological processes that depend on history such as evolution and ontogenesis, in contrast with those that are independent of history, like individual organisation. It questioned the organisations of living systems which made them a whole.
Varela et al pointed out autonomy as the characteristic phenomenon arising from an autopoietic organisation; one that is a product of a recursive operation. They described an autopoietic organisation as a unity; as a system, with an inherently invariant organisation. Autopoietic organisation can be understood as a circular organisation; as a system that is self-referential and closed. Jerome McGann, on the basis of his interpretation of Varela et al, described an autopoietic system as a “closed topological space, continuously generating and specifying its own organisation through its operation as a system of production of its own components, doing it in an endless turnover of components”.
What must be noted here is that the computational concept of self-reproducing automata is classically based on an understanding of a cell and its relation to the environment. This is akin to the conceptual premise of autopoiesis, which is the recursive interaction between the structure and its environment, thus forming the system. It must be noted that both the concepts start with a biological understanding of systems and then extend the concept. A direct link can be observed between the works of von Neumann, and Maturana and Varela. Automata, therefore, can be seen as an autopoietic system.
The sociologist, Niklas Luhmann, took forward this concept into the domain of social systems. His theoretical basis for the social systems theory is that all social events depend on systems of communication. On delving into the history of social or societal differentiation, Luhmann observes that the organisation of societies is based on functional differentiation. A “functionally differentiated society”, as he explains, comprises varying parallel functional systems that co-evolve as autonomous discourses. He discovers that each of these systems, through their own specific medium, evolve over time, following what Luhmann calls “self-descriptions”, bringing out a sense of autonomy in that respective system.
Following Maturana and Varela’s explanation, an autopoietic organisation may be viewed as a composite unity, where internal interactions form the boundary through preferential neighbourhood interactions, and not external forces. It is this attribute of self-referential closure that Luhmann adopts in his framework. This closure maintains the social systems within and against an environment, culminating in order out of chaos.
The Limits of Autopoietic Thinking
Beth Dempster, as a contradiction to Maturana and Varela’s proposition of autopoiesis, proposed a new concept for self-organising systems. She argues that heuristics based on the analogy of living systems are often incongruous and lead to misleading interpretations of complex systems. Besides, autopoietic systems tend to be homeostatic and are development oriented in their nature. Being self-producing autonomous units “with self-defined spatial or temporal boundaries”, autopoietic systems show a centralised control system and are consequently efficient. At the same time, such systems tend to develop patterns and become foreseeable. It is this development-oriented, predictable and bounded nature of autopoietic systems that poses a problem when such systems are scaled up.
Autopoietic systems follow a dynamic process that allows them to continually reproduce a similar pattern of relations between their components. This is also true for the case of automata. Moreover, autopoietic systems produce their own boundaries. This is the most limiting aspect of these concepts.
Autopoietic systems do not instigate the autonomy of parts, as they evolve on a prescribed logic. Instead, a more interesting proposition is one in which the interacting parts instigate a kind of feedback mechanism within the parts, leading to a response that triggers another feedback mechanism, and so on. Mario Carpo’s argument that in the domain of the digital, every consumer can be a producer, and that the state of permanent interactive variability offers endless possibilities for aggregating the judgement of many, becomes relevant at this juncture. What holds true in the context of autopoiesis is Carpo’s argument that fluctuations decrease only at an infinitely large scale, when the relations converge ideally into one design.
In the sympoietic context, however, this state of permanent interactive variability Carpo describes is an offer of the digital to incorporate endless externalised inputs. The need for sympoiesis comes in here. Sympoiesis maintains a form of equilibrium or moderation all along, but also, at the same time, remains open to change. The permanent interactive variability not only offers a multitude of situations but also remains flexible.
The limits to autopoietic thinking is what forms the basis for Dempster’s argument. In contradistinction to autopoiesis, she proposes a new concept that theorises on an “interpretation of ecosystems”, which she calls sympoietic systems. Literally, sympoiesis means “collective creation or organisation”. A neologism introduced by Dempster, the term, sympoiesis, explains the nature of living systems. Etymologically, it stems out from the Ancient Greek terms “σύν (sún, “together” or “collective”)” and “ποίησις (poíesis, “creation, production”)”. As Dempster explains, these are “collectively producing systems, boundaryless systems.”
Sympoietic systems are boundary-less systems set apart from the autopoietic by “collective, amorphous qualities”. Sympoietic systems do not follow a linear trajectory and do not have any particular state. They are homeorhetic, i.e., these systems are dynamical systems which return to a trajectory and not to a particular state. Such systems are evolution-oriented in nature and have the potential for surprising change. As a result of the dynamic and complex interactions among components, these systems are capable of self-organisation. Sympoietic systems, as Donna Haraway points out, decentralise control and information”, which gets distributed over the components.
Sympoiesis can be understood simply as an act of “making-with”. The notion of sympoiesis gains importance in the context of ecological thinking. Donna Haraway points out that nothing or no system can reproduce or make itself, and therefore, nothing is really absolutely autopoietic or self-organising. Sympoiesis reflects the notion of “complex, dynamic, responsive, situated, historical systems.” As Haraway explains, “sympoesis enlarges and displaces autopoesis and all other self-forming and self-sustaining system fantasies.”
Haraway describes sympoietic arrangements as “ecological assemblages”. In the purview of architecture, sympoiesis brings out a notion of an assemblage that could be understood as an architectural assemblage growing over sympoietic arrangements. Though sympoiesis is an ecological concept, what begins to work in the context of architecture is that the parts don’t have to be strict and they aim to think plenty; they also have ethics and synergies among each other. In sympoietic systems, components strive to create synergies amongst them through a cooperation and a feedback mechanism. It is the linkages between the components that take centre stage in a sympoietic system, and not the boundaries. Extrapolating the notion of sympoiesis into the realm of architecture, these assemblages can be conceived in Haraway’s words as “poly-spatial knottings”, held together “contingently and dynamically” in “complex patternings”. What become critical are the intersections or overlaps or the areas of contact between the parts.
Sympoietic systems strategically occupy a niche between allopoiesis and autopoiesis, the two concepts proposed by Maturana and Varela. The three systems are differentiated by various degrees of organisational closure. Maturana and Varela elaborate on a binary notion of organisationally open and closed systems. Sympoiesis, as Dempster explains steps in as a system that depends on external sources, but at the same time it limits these inputs in a “self-determined manner”. It is neither closed nor open; it is “organisationally ajar”. However, these systems must be understood as only idealised sketches of particular scenarios. No system in reality must be expected to strictly adhere to these descriptions but rather lie on a continuum with the two idealised situations as its extremes.
It is this argument that is critical. In the context of architecture and urban design, what potentially fits is a hybrid model that lies on the continuum of autopoiesis and sympoiesis. While autopoiesis can guide the arrangement or growth of the system at the macro level, sympoiesis must and should step in in order to trigger a feedback or a circular mechanism within the system to respond to externalities. What can be envisaged is therefore a system wherein the autopoietic power of a system constantly attempts to optimise the system towards forming a boundary, and simultaneously the sympoietic power of the system attempts to trigger the system for a more networked, decentralised growth and existence, and therefore, creates a situation where both the powers attempt to push the system towards an equilibrium.
Towards Poly-Spatial Knottings
In sympoiesis, parts do not precede parts. There is nothing like an initial situation or a final situation. Parts begin to make each other through “semiotic material involution out of the beings of previous such entanglements” or fused situations. In order to define codividuality and to identify differences, an understanding of classifying precedents is important. The first move is a simple shift from an object-oriented thinking to a parts-oriented thinking. Buildings are classified as having a dividual, individual and codividual character from the point of view of structure, navigation and program.
Codividual is a spatial condition that promotes shared spatial connections, internally or externally, essentially portraying parts composed of parts, which behave as one fused part or multiple fused parts. The fused situations fulfil the condition for codividuality as the groupings form a new inseparable part – one that is no longer understood as two parts, but as one part, which is open to fuse with another part.
Delving into architectural history, one can see very few attempts in the past by architects and urban designers towards spatial integration by sympoietic means. However a sympoietic drive can be seen in the works of the urban planner Sir Patrick Geddes. He was against the grid-iron plan for cities and practised an approach of “conservative surgery” which involved a detailed understanding of the existing physical, social and symbolic landscapes of a site. For instance, in the plan for the city of Tel Aviv in Israel (1925–1929), Geddes stitches together the various nodes of the existing town akin to assemblages to form urban situations like boulevards, thereby activating those nodes and the connecting paths.
Fumihiko Maki and Masato Oktaka also identify three broad collective forms, namely, compositional form, megastructures and group forms. Maki underscores the importance of linkages and emphasises the need for making “comprehensible links” between discrete elements in urban design. He further explains that the urban is made from a combination of discrete forms and articulated large forms and is therefore, a collective form and “linking and disclosing linkage (articulation of the large entity)” are of primary importance in the making of the collective form. He classifies these linkages into operational categories on the basis of their performance between the interacting parts.
Building upon Maki’s and Ohtaka’s theory of “collective form”, it is useful to appreciate that the architecture of a building can be thought of as a separate entity, and consequently there is an “inadequacy of spatial language to make meaningful urban environment.” Sympoiesis comes out through this notion of understanding the urban environment as an interactive fabric between the building and the context. Maki and Ohtaka also make an important comment that the evolution of architectural theory has been restricted to the building and describe collective forms as a concept which goes beyond the building. Collective forms can have a sympoietic or an autopoietic nature, which is determined by the organisational principles of the collective form. Sympoietic collective forms not only can go beyond the building, but also weave a fabric of interaction with the context. Although a number of modern cases of collective forms exist, most of the traditional examples of collective forms, however, have evolved into collective forms over time, albeit unintentionally.
The Corridor by Giorgio Vasari
An important case of an early endeavour in designing a collective form at an urban scale is Corridoio Vasariano by Giorgio Vasari in Florence, built in the year 1564. It can be understood as a spatial continuum that connects through the numerous important buildings or nodes within the city through a built corridor, resulting in a collective form. According to Michael Dennis, Vasari’s Corridor, in its absolute sense, is a Renaissance “insert” into the “fundamentally medieval fabric of central Florence”. As Dennis writes in The Uffizi: Museum as Urban Design (1980),
“…Each building has its own identity and internal logic but is also simultaneously a fragment of a larger urban organisation; thus each is both complete and incomplete. And though a
given building may be a type, it is always deformed, never a pure type. Neither pure object nor pure texture, it has characteristics of both – an ambiguous building that was, and still is, multifunctional…”
Dennis’s description for the design of the Vasari’s Corridor brings out the notion of spatial fusion of buildings as parts. The Corridor succeeds as an urban insert and this is primarily for two reasons. At first, it maintains the existing conditions and is successful in acclimatising to the context it is placed in. Secondly, it simultaneously functions on several varying scales, from that of the individual using the Corridor to the larger scale of the fabric through which it passes. The Vasari’s Corridor is a sympoietic urban fusion – one that is a culmination of the effect of local conditions.
Stan Allen, in contrast to compositions, presents a completely inverted concept for urban agglomerations. His concept of field configurations reflects a bottom-up phenomena. In his view, the design must necessarily reflect the “complex and dynamic behaviours of architecture’s users”. Through sympoiesis, the internal interaction of parts becomes decisive and they become relevant as they become the design drivers and the overall formation remains fluid and a result of the interactions between the internal parts.
Towards a Sympoietic Architecture
Another important aspect that forms a basis for the sympoietic argument is the relevance of information in systems. While Maturana and Varela explain that information must be irrelevant to self-producing systems since it is an extrinsically defined quantity, Dempster lays great emphasis on the relevance of information in sympoietic systems. Her explanation on the relevance of information is that it potentially carries a message or a meaning for a recipient. Information, therefore, is dependent on the context and recipient, but Stafford Beer hints that it is also “observer dependent”.
In the architectural domain, it signifies that information or external data input holds no relevance in an autopoietic system. The system grows purely on the basis of the encoded logic and part-to-part organisational relations, and is unrestricted and free from any possible input. However, information or data in the sympoietic paradigm gains relevance as it activates the system as a continuous flux of information guiding its organisation. This relates to the concepts of reinforced machine learning, wherein the system learns by heuristics to evolve by adapting to changing conditions, and by also producing new ones, albeit it comes with an inherent bias.
The Economic Offer of the Codividual
From an economic lens, the concept of sympoiesis does not exist at the moment. However, with the rise in participatory processes within the economy and the advent of blockchain, it shows immense potential in architecture. Elinor Ostrom’s work on the role of commons in decision-making influences the work of David Rozas, who researches on a model of blockchain-based commons governance. He envisages a system which is decentralised, autonomous, distributed and transparent, a more democratic system where each individual plays his/her own role. This idea is about bringing a more sympoietic kind of drive to blockchain. Sympoietic systems are based on a model that is akin to a commons-oriented or a blockchain-based economy that functions like a cat’s cradle with its multiple stakeholders being interdependent on each other. And as Jose Sanchez points out, it is the power of the discrete, interdependent system that makes this architecture possible. According to him, it offers a “participatory framework for collective production”.
The fusion of parts leads to the creation of parts such that the sum of the parts becomes greater than the whole. A codividual sympoietic model can potentially resolve the housing crisis since it flips the economic model to a bottom-up approach. With tokenisation, autonomous automatisation, decentralisation of power and transparency, this blockchain-based codividual model can compete with traditional real estate models, thereby resulting in more equitable and fair-minded forms of housing. As Lohry and Bodell point out, such models can reduce personal risk and also make livelihoods more economical and “community-oriented”.
The ecological framework of the concept of poiesis, as already outlined, is based on the growth from the organisation of elements. In the context of autopoiesis and sympoiesis, it can be observed that “part-to-part” and even “part-to-whole” conditions gain significant relevance in these concepts. An appreciation of these conditions, therefore, becomes relevant to understand these kinds of notions. The idea of components, as described by Dempster and Haraway in the purview of sympoiesis, and Jerome McGann in the autopoietic context, could be extended to architecture in the form of part-thinking.
However, a mereological approach begins with existing entities or “sympoietic interactions” and proceeds further with a description of their clusters, groupings and collectives. Through codividual sympoiesis, the whole gets distributed all over the parts. In this system, the discreteness of parts is never just discrete. It goes beyond the participating entities and the environment. In line with Daniel Koehler’s argument, the autonomy of the part ceases to be defined just as a self-contained object. It goes beyond it and begins to be defined “around a ratio of a reality, a point of view, a filter or a perspective”.
Sympoiesis evolves out of competitive or cooperative interactions of parts. As in ecology, these parts play symbionts to each other, in diverse kinds of relationalities and with varying degrees of openness to attachments and assemblages with other fusing parts depending on the number of embedded brains and the potential connectors. Traditionally, architecture is parasitic. When the aesthetic or the overall form drives the architecture, architectural elements act as a host for other architectural elements to attach to depending on composition. In sympoiesis, there is no host and no parasite. It inverts the ideology of modernism, beginning with not a composition but actually evolving a composition of “webbed patterns of situated and dynamic dilemmas” over symbiotic interaction. Furthermore, increasingly complex levels of quasi-individuality of parts come out of this process of codividual sympoiesis. It gives an outlook of a collective and still retains the identity of the individual. It can simply be called multi-species architecture or becoming-with architecture.
Talking of transdisciplinary ecologies and architecture, we can foresee string figures tying together human and nonhuman ecologies, architecture, technologies, sustainability, and more. This also gives rise to a notion of ecological fusion of spatial conditions such as daylight and ventilation, in addition to physical fusion of parts. Codividual sympoiesis, thus, even shows potential for a nested codividual situation, in that the parts sympoietically fuse over different spatial functions.
Going over sympoiesis and mereology, it makes sense to look for parts which fuse to evolve fused parts; to look for architecture through which architecture is evolved; to look for a codividuality with which another codividuality is evolved. From a mereological point of view, in a system in which the external condition overlaps with an internal part in the search for another component, to give rise to a new spatial condition over the fusion of parts could be understood as codividual sympoiesis. Codividual sympoiesis is therefore about computing a polyphony, and not orchestrating a cacophony.

Mereology is a formal concept which enters architecture as an additional formal category. Form is a rather ambiguous concept in architecture. So in this essay, first an investigation is conducted by contrasting two closely related concepts: shape and content.
Hans Trusack criticises the problem of shape for its shallow formalism and historical-theoretical indifference as a defensive strategy that evades the disciplines and difficulties of past and future. The distinction between the terms “form” and “shape”, following Tursack’s argument, is a “matter of generative process”. Both terms point to the production of visual expression. Yet while shape refers to the appearance of an object, form reflects the logic of transformation and operation within historical and theoretical contexts such as political and religious ideology, economics and technological background. Tursack criticised the strategy of shape in architecture, stating its lack of reference, it being “plainly, and painfully, evident”, and incapable of moving forward. Whereas form is difficult, disciplinary and requires historical and theoretical study, and yet promises the future.
Form has the advantage of being able to deal with complex relations due to its deep and continuously evolving intervention with content. The term form derives from the Latin word forma, is understood as the combination of two Greek words: eidos, the conceptual form, and morphe, the physical form. The complexity of form can be attributed to these differentiated meanings, yet complexity is compatible with agencies and relations. This can emerge further by conducting a brief historical review.
Ancient Greek architecture pursues the ideality in mathematics and proportion. The efforts made by architects in designing the Parthenon provides evidence of this feature. These operations tried to approximate the physical shape of architecture to the “ideal” form. Form reflects the pursuit of ideality and perfection in this period.
For Gothic architecture, there were more concerns about structure, and matter was pushed to its maximum capability to build as tall as possible for religious appeal. Consequently, structures were designed to be rigid and lightweight, and solid walls were replaced by glass windows, while flying buttresses supported the main structure to grow even taller. Consequently, astonishing space and fascinating transparency emerged.
Modernism claims that “form follows function”, rejecting traditional architecture styles. The reality of matter and the logic of technology eschewed decorations, proportions, or any subjective distortion of matter. The emphasis on the term “function” illustrates an ideology of treating architecture as a machine. Each part is nothing more than a component that has a certain feature inside this machine, and redundant decorations and details are removed to deliver this idea clearly. Without distractions, space becomes evident.
In the shift to postmodernism, the uniformity and the lack of variety of modernist architectures were reacted against, and a great variety of approaches emerged to overcome the shortcomings of modernism. Parametricism, for instance, has been promoted by the thriving of digital technologies. Designers are capable of more complex formal production, and architectural elements have become variables that can be interdependently manipulated. In this formalism, rigidity, isolation, and separation are opposed, while softness, malleability, differentiation and continuity are praised.
From the examples above, form is the embodiment of the relations between architecture and its motive in specific historical scenarios, while for shape, only the results are accounted for – relations are ignored, and architecture is treated as isolated physical entities, incapable of producing new relations. Different methodologies of dealing with architectural form also imply the variation of ideology in compiling form with content.
Mereology – An Approach of Architectural Form
In recent philosophical texts, a third notion of form is brought forward. Contrary to a dialectic of form and content, here investigations deal with the resonance of parts: the description of objects by their ontological entanglement only. The writings of the philosopher Tristan Garcia are a strong example for such mereological considerations. In his treatise Form and Object: A Treatise on Things (2014), Garcia investigates the ontology of objects with two initial questions, “… what is everything compose of? … what do all things compose?” The first question interrogates the internal, the elementary component of everything. The second interrogates the external, the totality of everything. For Garcia, the form of a thing is “the absence of the thing, its opposite, its very condition,” form has two senses, the “beginning”, and the “end”, which never ends. Form begins when a thing ends, it begins with different forms; in the end, since it has “endless end”, form ultimately merges into one, which is “the world”. Garcia defines an object as “a thing limited by other things and conditioned by one or several things.” The form of an object depends on what comprehends or limits this object. Every object is “embedded in a membership relation with one or several things”, they can be divided by defining limits, which is also a thing distinguishing one thing from another. Garcia’s argument adapts the concept of mereology. Form has two extremes, one toward the fundamental element of matter, and the other toward the world, comprehending everything. All things can always be divided into an infinite number of parts, and they can always be parts of another thing. Identifying parts or wholes within a section we can operate on can establish a limit. The relevance between form and mereology opens a new opportunity to inspect architectural form from a different point of view.
One of the first discussions about parts and wholes in modern philosophy was posed by Edmund Husserl, in Logical Investigation (1st ed. 1900-1901, 2nd ed, 1913), but the term “mereology” has not been put forward until Stanisław Leśniewski used it in 1927 from the Greek work méros (parts). Mereology is considered as an alternative to set theory. A crucial distinction lies between mereology and set theory in that set theory concerns the relations between a class and its elements, while mereology describes the relations between entities. The mathematical axioms of mereology will be used as the fundamental theory of developing the method of analysing architectural form.
Following Roberto Casati and Achim Varzi, the four fundamental mathematical formularisations of mereology are: “Relations are reflexive, antisymmetric and transitive. (…) First, everything is part of itself. Second, two different objects cannot be part of each other. Third, each part of a part of a whole is also part of that whole. Fourth, an object can be a part of another object, if both exist.”
Mereology can be a promising approach also for the reading of architectural form, as it emphasises relationships without reducing buildings to their appearance or function. However, such philosophical descriptions consider wholes and parts as mostly abstract figures. Therefore, a supplement could be developed to properly categorise the mereological relations in the field of architecture. Having the relations between form and mereology addressed, methodologies can be developed to access the analysis of architectural form. Mereology as a specific methodology for architecture is quite new. One of the first introductions can be found in Daniel Koehler’s book The Mereological City: A Reading of the Works of Ludwig Hilberseimer (2016). Here, Koehler departs from the modern city, exemplified through the work of Ludwig Hilberseimer to illustrate mereological relations in the modernist city. From the room to the house to the city to the region, Hilberseimer canonically drew the city as a hierarchical, nested stack of cellular spaces. However, through the close reading of its mereological relations it becomes clear that political, economic or social conditions are entangled in a circular composition between the parts of the city. Recalling Garcia’s discourse, and resonating with Leon Battista Alberti’s thesis, Koehler shows that the cells in Hilberseimer’s modernist city are interlocked. A house becomes the whole for rooms; a city becomes the whole for houses. By considering the city and its individual buildings equally, “the whole is a part for the part as a whole.”
Architectural Relations Between Parts and Wholes
Parts are not only grouped, packed and nested through different scales, but also in different relations. Specific relationships have been developed in different architectural epochs and styles. Mathematically, four general classes of relations can be drawn: whole-to-whole, part-to-part, whole-to-parts and parts-to-whole, while more specific subclasses can be discovered from each.
According to the mathematical definition, between wholes there exist complex relations, the whole could exist on any mereological level, and the complexity of relations between multiple levels are also accounted for. Whole-to-whole relations can become complex when considering multi-layer interaction, and more relations can be identified: juxtapose, overlap, contain, undercrossing, transitivity, partition, trans-boundary, intact juxtapose, compromised juxtapose.
A first glance of New York, gives the impression that it is quite heterogeneous, but underneath there is a city grid underlying the heterogeneity, and while the relations displayed in the grid are rather simple, all wholes juxtapose with one another. In comparison, in Siena, an Italian city, the urban space is quite complex, where boundaries of all wholes negotiate with others, the gaps in between are carefully treated, the nesting relations are extremely rich, and multiple relations from the diagram above can be found.
The whole-to-parts relation studies what the whole does to its part, namely in terms of top-down rules. The mathematical definition does not involve specific situations that a whole-part condition holds. Distinctions within individual contexts make a significant difference in clarifying an explicit relation. The situations for the whole can generally be classified into following types: fuse, fit and combine.
One of Zaha Hadid’s projects, Heydar Aliyev Centre, indicates the fusing relation. Architecture is represented as a smooth, fluid volume. The distinction between elements disappears, and this dominating power even extends to the external landscape. In order to maintain a continuous whole, parts are fabricated into a particular shape, having their unique unchangeable locations. The continuous whole excessively overwhelms the parts, yet not all parts are reshaped to fuse into the whole, and because the parts are small enough in relationship to the whole, the control from the whole is weakened, and parts are fit into the whole.
The third type is combining. An example for this relation is Palladio’s project Villa Rotonda. In this case, parts are obvious. The whole is a composition of the parts’ identities. However, the whole also holds a strong framework, in a rigorous geometric rule that decides positions and characters of parts. The arrangement of parts is the embodiment of this framework.
The parts-to-whole relation studies what the parts do to the whole, or the power of bottom-up relationships. The different situations of parts are also key parameters in validating a given relation. The classification of situations for parts are as follows: frame, intrinsic frame, extrinsic frame, bounded alliance, unbounded alliance.
Emil Kaufmann thoroughly investigated the innovative works by Claude Nicholas Ledoux in Three Revolutionary Architects: Boullee, Ledoux and Lequeu (1952). According to Kaufmann’s study, Ledoux’s works developed new compositional relations of elements from the Baroque. The characteristics of parts in Baroque architecture are rich, but tend to regulate the identities of all the elementary parts and fuse them together to serve the harmony of the whole, presenting the intrinsic framing. Ledoux’s work is an extrinsic framing, where the parts are relatively independent, with each element maintaining its own properties, and while consisting of the whole, they can be replaced with other identical components.
One of my projects in discrete aggregation of elements presents an unbounded alliance relation. The aggregation as a whole shows a form that is discretised (Figure 12), and does not pass any top-down instructions to its parts.
Part-to-Part Without Whole – The Ultimate Parts
For part-to-part relations, local interactions are emphasised, and interactions occur at multiple levels of compositions, where the part-to-part relations in some cases are similar to that between wholes. It has following classifications: juxtapose, interrelate, contain, partition, overlap, trans-juxtapose, over-juxtapose, over-partition, over-overlap.
Architects have been working on the possibility of removing the whole by studying the part-to-part relations. Several approaches have been developed, mainly through computation. Neil Leach considers the city as a “swarm intelligence”, bringing forward the potential of developing urban form with computational method. Leach encourages swarm intelligence for the interactions between agents (parts), which “offers behavioral translations of topology and geometry”, while fractals, L-systems or cellular automata are all constrained by some limitation. However, although swarm intelligence is based on the interaction of individual agents, it is always treated as a whole; all cells of CA are fixed in the background grid, which is also a whole. For fractals and L-systems, they can be subdivided into infinite parts, a transcendent whole where all parts grown from still exist. In the mereological sense, none of these cases can escape the shadow of the whole – strictly speaking, they are part-to-whole relations. To discuss the part-to-part relation in more depth, more investigation is needed to clarify the concept of part.
In The Democracy of Objects (2011), Levi Bryant claims that objects constitute a larger object by establishing relations with others, but this doesn’t alter the existence of objects, as he says, “all objects equally exist, but not all objects exist equally.” In Bryant’s discourse, this independence suggests the dissolution of the whole. Bryant proposes a concept of “regimes of attraction”, that includes the “endo-relation” and the “exo-relation”. The endo-relation indicates that the proper being of an object consists of its powers or what an object can do”, not the “qualities” emerging within an exo-relation. An object possesses “volcanic powers”, the stabilisation of the regime of attraction actualises it into a specific state. The concept of the whole reduces objects to this state, which displays only a section of their proper beings. The concept of regimes of attraction is against this reduction.
The regime of attraction can be linked to the notion of “assemblage” from Manuel DeLanda, however, there is a distinction between the two. Assemblage holds only the relation of exteriority, whereas regime of attraction maintains both relations of interiority and exteriority. In Assemblage Theory (2016), DeLanda reassembled the concept “assemblage”, which was originated from the French agencement. Created by Gilles Deleuze and Félix Guattari, this original term refers to the following meanings: the “action of matching or fitting together a set of components” – the process, and the “result of such an action” – the product.
DeLanda emphasised two aspects, heterogeneity and relations. As he indicated, the “contrast between filiations and alliances” can be described in other words as intrinsic and extrinsic relations.
The nature of these relations has different influences on the components. The intrinsic relation tends to define the identities of all the parts and fix them into exact location, while the extrinsic relation connects the parts in exteriority – without interfering with their identities. DeLanda summarised four characteristics of assemblage: 1) individuality, an assemblage is an individual entity, despite different scale or different number of components; 2) heterogeneity, components of an assemblage are always heterogeneous; 3) composable, assemblages can be composed into another assemblage; 4) bilateral-interactivity, an assemblage emerges from parts interactions, it also passes influences on parts.
DeLanda then moved on to the two parameters of assemblage. The first parameter is directed toward the whole, the “degree of territorialisation and deterritorialisation”, meaning how much the whole “homogenises” its component parts. The second parameter is directed toward the parts, the “degree of coding and decoding”, meaning how much the identities of parts are fixed by the rules of the whole. The concept of assemblage provides us a new lens of investigating these mereological relations. With this model, the heterogeneities and particularity of parts are fully respected. The wholes become immanent, individual entities, existing “alongside the parts in the same ontological plane”, while parts in a whole are included in the whole but not belonging to it, and according to Bryant’s discourse, the absence of belonging dispelled the existence of the whole.
From the study of regime of attraction and assemblage, this essay proposes a new concept – “the ultimate parts” – in which a proper “part-to-part without whole” is embedded. A part (P) horizontally interacts with its neighbouring parts (Pn), with parts of neighbouring parts (Pnp), as well as interacting downwardly with parts that compose it (Pp) and upwardly with wholes it is constituting which are also parts (Pw). This concept significantly increases the initiatives of parts and decreases the limitations and reductions of them. It doesn’t deny the utilities of the whole, but considers the whole as another independent entity, another part. It’s neither top-down, nor bottom-up, but projects all relations from a hierarchical structure to a comprehensive flattened structure. The ultimate parts concept provides a new perspective for observing relations between objects from a higher dimension.
One application of this concept is TARSS (Tensegrity Adaptive Robotic Structure System), my research project in MArch Architectural Design in B-Pro at The Bartlett School of Architecture in 2017–2018. This project utilises the features of tensegrity structures of rigidity, flexibility and lightweight. The difference is that rather than fixing parts into a static posture and eliminating their movements, the project contrarily tries to increase the freedom of parts as much as possible. The tensile elements have the ability to adjust their lengths collaboratively to change the general shape of the aggregation. Reinforcement learning is employed to empower the parts with objective awareness. The training sessions were set up toward multiple objectives that are related to architectural concerns, including pathfinding, transformation, balance-keeping, self-assembling and structural load distributing. This approach brings obvious benefits, as architecture design in this sense is not only about an eventual result, but about the dynamic process of constantly responding to the environmental, spatial or functional requirements. The premise is to treat parts as ultimate parts whilst retaining their objectivity and being able to actively interact at all mereological levels without limitations.
The concept of ultimate parts brings forward a new relation of “part-to-part without whole”. This new relation belongs to a higher dimension. The details and essence of objects are simultaneously displayed, without being obscured by the compositional structure. Analogised with spatial dimensions, a 3-dimensional cube simultaneously shows all its faces and interior in 4-dimensional space. The significance is that it opens vast new perspectives and operational methodologies in the architectural design realm. Especially with the advancement in robotics and artificial intelligence, this type of new relationship enables greater opportunities by regarding machines as characters with immense potential to work with us, instead of for us. The role of designers would be very much like “breeders of virtual forms”, who do not rule the form, but guide it towards the demands. This moves away from anthropocentric design by overcoming part-to-whole with part-to-part.

This interview took place on April 11th, 2017 at the office of Herman Hertzberger in Amsterdam, with questions by Daniel Koehler.
Daniel Koehler: After all your years as a teacher, maybe it would be a good departure for conversation if you can tell us what is your favourite exercise for teaching architecture?
Herman Hertzberger: Well, my favourite exercise is making a housing environment, where small children could live and play outside. This is an old-fashioned thing, but I am absolutely convinced that children should play in the streets in order to find out about the world and to learn about the good and the bad things that exist. I am afraid that today in urbanism you find high-rises, and the immense distance from the living unit to the street is a problem. Consequently, cities only have playgrounds with fences around, and there children are safe to play. But the world is not only about safety, the world is about finding out how far you can go in your life.
Can you tell us a little bit about how you began to communicate as a group during the beginning of structuralism?
We started a school! We had seminars for discussion, where everyone brought in something to discuss. And then we had the Forum editorial staff. There was Aldo van Eyck, Jacob Bakema and others who are less well known (Dick Apon, Joop Hardy, Jurriaan Schrofer and Gert Boon). There was an enormous amount of communication. Every Tuesday night we saw each other with no exception, where we discussed the next issue of the magazine.
And, what was the relevant media at the time you started to develop your ideas?
Magazines were very important. We used to have three or four Dutch magazines, two French, two English, one American, two Swiss, two Italian. They were all on the table. “Did you see that building? I think it is good.” And then we had a discussion. Today we still get some magazines, but today you get all the information from around the world in one click. That is fantastic, the possibilities today are just immense. It is more information, a lot of pieces of an enormous puzzle. But is it also possible to put it together? I hope the younger generation can.
The magazine Forum was for me a sort of postgraduate study. At that moment I started to see the work, the hands and eyes of real architects. That helped me to start thinking. And there were connections to many other architects from all over. There were conferences, and there you saw people. At Delft University, where I was teaching, we invited all the architects we were interested in. We are still doing this.
When one reads the current literature, one can draw two different issues. On the one hand a common critique of functionalism in architecture, and on the other hand, the influence of new ideas coming from sociology. Would you say that this enormous explosion of ideas and diversity of projects was a response to architectural problems or were these new concepts coming from other fields prescriptive to your projects?
First of all, there is nothing coming from sociology. I have little or no connection to sociology. Sociology is the science of human relations. But you do not need to go into this science as an architect. Architecture is a matter of using your eyes and ears to look into the world and see what needs to be done. But today, architecture is driven by algorithms and rules. All the rules, saying you should do this or that, you are supposed to not do this. Architecture is then reduced to problem-solving. You must be aware of that mistake. Architecture is not problem-solving. Of course, you have to solve problems, but this is only one aspect of architecture. It starts to be architecture when it provides more freedom to people, opening the possibility that things are getting better than they were before.
Can you give an example?
A dwelling needs to have a balcony. Why? To let people go outside, and there are rules about the size of your balcony. Most architects think: well, I included a balcony. But they should base the form and dimensions of a balcony on the needs of daily life. Such as sitting in a corner without being seen by others or not being disturbed while reading your book yet with the possibility of having contact with your neighbour. Second, you may want to be able to have a meal with your family. You maybe want to have flowers and plants. In a way, this is culture. Make that list, and when you design a balcony, be sure that all the points you have listed have also been fulfilled. In this way you increase people’s freedom. Most balconies do not do that. On most balconies all you can do is sit. Most architects don’t think, they don’t look at what is going on. And then, of course, the developer says, “It should not cost more, so we have to make it small.” So I have rules independent of the developers. For me, it starts to become good when those rules are going to be met. This method works for every part of the building, from a dwelling, to a living unit, to a street, to the school. In a school, you can design where the black board in a classroom is going to be. And you have to think about what a school might be. I don’t need sociologists for that. Sometimes, sociologists can tell you some interesting things, but you have to think, and in the first place, look for yourself.
Your communal spaces are famous for their human scale, like the doorstep. I think that this down-scaling of the city to elements of a building enables you to design the building as an open system. For me, it seems you draw a difference in creating a building as a building and designing a building as a city.
For me, city, architecture, and building are very much related. Aldo van Eyck believed that making architecture is always making things more inside than before. Aldo van Eyck said, “Whatever you do, it is supposed to always increase the inside quality.” When you want to go outside, you go to the fields. There you have the horizon, you have the clouds and the openness. A city is for exchange – exchange of goods, of ideas. Cities are mostly based on trade, and on having a cinema, having shops, having communal things, being together.
Aldo van Eyck also claimed that the city should be a big house. I think that is a dangerous thing to say because the city is not the house where you are yourself, or where you are enclosed. The city should never be enclosed but always open, in connection with the whole world. It is the place where you see the airplanes flying above you. But it is an inside space in relation to the open field. And a building is, in fact, a small city. Make a building as a small city to have the emphasis lay on communication and exchange.
But most buildings are private territories with public corridors. How narrow can a public corridor be? It cannot be a centimetre larger, because this would cost money. Means of communication are considered extra. You can sell the dwellings but not the corridors. As a result, most buildings have very beautiful apartments and very small corridors. I am pleading for buildings where the corridors are streets. I try to put more emphasis on the communal spaces in a building.
When you consider a building as an open system, what role does the boundary between inside and outside have? Do you think that these open systems have an outside or do you think of them as endless? What is their relationship to the context and environment?
City is not just buildings but the space in between the buildings as well. The edge of building is forming the space of the city. You have to conceive of the edge of a building not as an end where the outside starts. You must see it the other way around, as a wall in the interior space of the city. The idea of the building as city is to put buildings in such a relation that the space in-between them is as important. This is something that is completely lost. It is also considered nostalgic. But look to New York. In New York, you have these high skyscrapers, but you also have very nice streets. When I am in Manhattan, I feel quite enclosed. That is because of the very strict system of the grid, and the building lines by which the streets are defined, and the blocks in between are open.
In one of your articles [Open City, 2011], you rightly point out that most of today’s housing projects consciously exclude communal spaces, and focus only on the assembly of private areas without any spatial linkages between them. Private areas are protected to one another rather than connected. A common – and I think dangerous – justification for such a design refers to changed economic circumstances, and most cynically, to the death of the welfare state. Would you say architecture is so dependent on economics?
Every square meter is supposed to generate a fee, so public space will be reduced to a minimum. Architecture has become business. And that makes the position of the architects to contribute to better spaces and towns very difficult.
But then architects are even more important.
Important as long as you are able to be aware of what sort of culture you are living in. I cannot give you the answer what to do. You have to explain and fight. But you need clients who believe in the architect. Things are very materialistic today. But there are also very interesting initiatives. For example, in Rotterdam, you have these old industrial halls which could be reused without high costs. Add a little paint, and it works. There are ways today that are contradicting this idea of architecture as economics. There is a lot for you to invent.
When I told a friend that we will visit you as one of the main protagonists of structuralism, his response was: ‘Wait a moment! Herman Hertzberger is not a structuralist; he is a humanist.’
Can you not be a structuralist and a humanist at the same time? Is this contradictory?
I think what my friend was pointing at is that there is a difference between structuralism as a style and structuralism as modus operandi, as a form of organisation and composition.
Style has to do with aesthetics, but aesthetics is a pitfall. Most architects think making something beautiful is all that architecture is about. But you can’t make something beautiful, it is impossible. That doesn’t work. What you can do is make a painting which is striking, and shows you something you never saw before that makes you happy or fall in love with the painting, and then we decide this is a beautiful painting. But in architecture, don’t spend energy on trying to make something beautiful. Make it work. Then you may hope that someone says this is beautiful. For instance, the composer of music Arnold Schönberg said, “Do not do what others consider beautiful, but just what is necessary to you.” I like a building because it works. When someone if I think it is beautiful, then I say, when you are in love it is going to be beautiful. Beauty comes as a result. But you cannot say, now I am going to make it beautiful. Beauty is a pitfall for architects.
Structuralism means there are simple rules that enlarge the amount of free space that you can achieve. I took the grid as an example earlier. The very rigid system of the grid allows you to be more free in the blocks in between. All of the blocks can be different; some high, some low. It is an enormous mosaic of possibilities that is held together by the grid. When you know what rules you have to use, you can be creative. It is a misunderstanding that the one contradicts the other.
It is interesting that you describe a rule as a form of enclosure, as a form of an inside.
If something is not limited you create chaos. Rules prevent you from chaos, and within rules you can be creative. Noam Chomsky [the linguist] uses the words competence and performance. The structure of language is its competence, it is its capacity to express. And performance is what you are actually expressing with it. In language you have grammar, but every individual talks in his or her personal way using the same rules.
Would you say that you have a grammar and vocabulary then? Do you have certain elements that you are frequently using? You were talking earlier about balconies and streets. In your work do you consider elements repeat structurally, which can re-emerge in different styles, but with similar performance? Or do you begin each project with a new grammar?
I do not use the same grammar for every building. I could, but I want to try different things. There are many people who thought housing should be produced in a factory, like cars. It is such a simple idea. But it doesn’t work, because every location has its own needs, whereas a car is the same everywhere. So, you can not use the same grammar. I use another grammar for a school and another for housing for instance. Some things have a similar grammar, like how you make a door, which works in most cases.
Do you have a particular vocabulary of elements that reappear during your career in different articulations and styles?
Architecture should accommodate people and things that people are concerned with. I use this everywhere. To give you a simple example: when I make a column, most of the time I design it with a base for people to be able sit on it. This is for me an accommodating device. It always works. This sort of thing is universal in my opinion: the idea of accommodation. Another example is the handrail of a stair. I always make a handrail that guides you where to go, making the end of it in such a way that even without looking you have the feeling that this is the end of the stairs. Everything I do tries to consider how it works for people. However the point is that it should be friendly to people, but not soft.
Friendly architecture! This is a wonderful conclusion. Thank you, Herman Hertzberger for sharing your time and thoughts with us.
