ABSTRACT This project aims to bring Metabolism to the 21st century, where their philosophy of impermanence and continual adaptation is ever more relevant to the fastpaced society we live in today. In the move towards post-capitalism, the needs of individual users will change, and will change more rapidly – requiring a spatially and tectonically responsive architectural system. Technology used for construction has barely changed compared to the motor and electronics industry. The process in which buildings are built, the way the components are fabricated to the way design process is managed and post-construction management is made, is efficient economically in a capitalist sense, yet lacks the ability to cater to the needs of the actual users. Metabolist projects such as the capsule tower or the Takara Beautillion by Kisho Kurokawa attempted to create adaptable architectures by using large prefabricated spaces that can be redesigned and reattached to a megastructure when required. The problem with this however, is that redesigning specific capsules becomes labour intensive and requires demolition (designing new capsules), making it very similar to construction processes that have been continually used from before. Digital metabolism aims to break down the unit of a capsule and megastructure further to even smaller, less specific pieces. Pieces that are small and generic on their own, that can be configured into structurally and spatially different dwellings, removing the need for predefined spaces. Structurally, robotically bent steel tubes will be used to form a shell like structure, where the individual tubes come together to form a structurally homogeneous whole. These tubes will be designed in such a way that their densities can be controlled dependent on the differing structural loads placed upon them. The process in which these structures are designed will be fully automated, where the user will be given more agency in the immediate sense of designing their spaces through a user accessible interface in which they can interact and control an otherwise complex system. The automation will occur from the initial design stage through to construction, to post-construction management and modifications. The user will intuitively configure the space, while behind the scenes the structural densities and construction sequences are simulated and automated. These tubes, or rod like geometries will then form the basis for the control of the inhabitable space itself, through using the same geometries as the steel tubes for structure but now can be varied in length. By using other materials such as timber, this allows very specific and localised control of spacial qualities such as porosity in a volumetric way. The process aims to allow complex volumetric operations to be made by the user in a intuitive way, giving true meaning to responsive and adaptable architecture; one which can be directly controlled by the user at will, when desired. The system allows the architecture to be impermanent, constantly adapted and tailored to whom the architecture is for – the end-user.

In order to understand previous examples of modular and resilient architecture, numerous case studies have been researched to understand the production chains and tectonic adaptability of the projects.
buildings to individual rooms can be removed and re-attached to different structures. There is a large amount of flexibility in the utility and arrangement of parts. However, flexibility in terms of the layout and form of parts are lacking.
One notable case study is the Metabolist’s Takara Beautillion by Kisho Kurokawa.
One of the biggest issues with the capsule architecture of the metabolists is the actual dwellings having to be completely redesigned as society or users change. The
Due to the plug-in nature of the parts, whole
one type fits all typology still exists, making the actual adaptability over time difficult to achieve.
The houses in this project had a requirement to be flexible, to accommodate for the subsequent expansion needed by the residents with their low income. For the value appreciation to be successful, the design of the initial structure was required to be innovative spatially.

CASE STUDY
ELEMENTAL (2003)
The flexibility within the structure is highly flexible compared to Park Hill, as the user will be able to decide what layout they would like to build before the spaces are defined. The adaptation of partitions is possible due to the ownership of the apartment being with the users. The flexibility not only extends to layouts, but also offers potential for uses other than inhabitation, such as trade workshops in the case of B1.1, or subletting in B1.2, further increasing the user’s income.
Land value high due to optimal location to city. Location required for residents to earn enough for expansion, and for property value to rise.

The use of shape grammars to generate designs for fabrication allows simple parameter changes to customize the desired spaces. This allows the user to be much more involved in the design process, offering options for mass customization. This makes for a very user accessible means of democratizing production (to an extent), where theoretically once the system is in place, architects will not have to intervene. This can work in a commons environment,
where prosumers have access to controlling their desires, and developers are able to create further rules and algorithms for generating new design options. This can be compared to a digital version of personalization, where the engineers create the finishes for use in construction; users working with architects to design a building to their tastes.

EXPANSION NOT POSSIBLE
Using mass housing to quickly house large amounts of people was a quick-fix solution to the housing crisis, not preparing for the future changes in society. Prefabricated concrete, the structural framework in which the building has been constructed with is incredibly rigid, and to make any modifications to layout, large amounts of demolition is required. In this sense, the traditional terraced house is more flexible. The layout still allows
for expansion in a less intrusive way, and the resident also has ownership over the property; making it legally much more easier to make changes. Although the mass housing typology presented itself as radical at the time, it was simply a continuation of the terraced house typology made possible with a different construction system.

The aim of this project is to create a construction system for dwellings which is resilient and adaptable in the movement to wards a post-capitalist society. The assumptions are that we have moved to a near zero marginal cost society as production adapts to renewable energy and circular economy based design from the current wasteful modes of production.
PRODUCTION CHAIN
TOWARDS A WHOLLY DIGITAL SYSTEM
Within design for a circular economy, the re-usability, scalability and flexibility of the construction system are key issues to be solved. By the production system being adaptable and re-usable, the dwellings themselves are able to much faster change or grow over time, adapting not only to society, but the differing needs and use-cases of each individual user.

Ownership of the dwellings will be virtual, where each individual user owns their appropriate share of the dwelling. This allows the easy addition or subtraction of users in shared dwellings, as well as allowing the users to virtually take their dwelling to any other location they wish to live in. The total asset a user has will be the sum of the value/m3 of the land their parts occupy, the total volume of the parts rather than individual parts – as dependent on the
geometry of the dwelling the amount of parts will change + in multi-storey dwellings parts must be used for circulation and connection of multiple blocks. The cost of the structural parts is to be levelled out throughout all users of the system.

For the system to be scalable, the largest issue identified was how the system will structurally respond to increasing loads as the building may grow.
as the base part, used to create metaparts which can be adjusted in density for the structural system to be responsive as a whole.
This requires a part system which is able to have the correct amount of strength at different parts of the building dependent on the loads happening.
The meta-parts are assembled on-site robotically, where the small scale of the pieces allow for the modification of the apartments after construction to take place while providing minimal disruption to the adjacent users.

BUILDING CONFIGURATION
This system aims to create multiconfigurable architectures able to be deployed efficiently. In order to make this possible, knowledge from the highly specialized consultants must be unified under a single system, involving not only collaboration between engineers, but collaboration with software engineers and managers to automate and computerize the processes involved in construction. This will be a highly ambitious endeavour on a large scale, requiring coordination between a very large number of consultants of all disciplines, resulting in a noticeable shift in the construction industry.

BIM TOWARDS FULL AUTOMATION
PHYSICAL/DIGITAL HIERACHIES AND BIM TO CONSTRUCTION WORKFLOW
Current procurement routes focus on different ways of managing different consulting companies. While this has been inevitable until now due to the high complexity and specialization in each discipline, in the move to full automation these consultants must be able to work together much better than what is currently possible.
This level of collaboration will reach the current holy grail of BIM, level 3 - full collaboration between disciplines shared in a single project model on a centralized repository, removing the problems of the ownership of information. The system takes the understanding and thinking of digital processes in BIM to the physical building, allowing a more continuous flow between different projects and their life-cycles within the system.

SPACE PLANNING SYNTAX
META-PART TO CHUNK
In design stage, meta-parts are arranged to form adjustable building chunks, where the dimensions can be adjusted according to need. Architect configured circulation and plumbing intensive spaces are designed as options for initial user selection. In the example to the right, the system outputs configuration that allows these spaces to be connected at a half height split,
allowing a degree of privacy between the eating and lounging spaces while keeping it open. Toilets and showers are placed on these levels as to minimise length of plumbing. The user configures the building chunk assemblies to their own personal preferences, while the system checks for structural or spatial errors in the background.

Individual meta-parts taken from the space model contain truss geometries described to the right, where the orientation and location of the geometry is identified in the spacial model, and the local structural loads are identified in the structural model. The analysis identifies the level of the density the meta-part must be increased to, which is fed back into the spacial model as to provide an organized model showing the density configuration of each meta-part.

Truss geometries of the structural parts are embedded in the massings of the metaparts. This forms the general structure of the building as a whole. The elements work in a discrete voxelized field, allowing localised increases in density depending on the loads placed. The discrete elements in this case allow the structure of the building to act homogeneously over the entire building, compared to continuous systems of space frames where the elements have specific use functions, such as a roof or a slab.

The geometric syntax of the structural part system is further developed to control interior space more volumatrically, by using the same geometries but in timber, allowing for very specific adjustments in porosity to be made to the dwellings.

OUTPUT ASSEMBLY INSTRUCTIONS
As the system is designed to allow users to easily interface with a complex system which modifies space in a volumetric way, there are many opportunities for the system to collect data on the user’s personalities, habits and preferences. This data can be used to initially give suggestions to how a user might want to manipulate their space, where in the future the integration of machine learning will allow the system to predict and automatically deploy modifications to the
spaces. Interactions with the system can be further simplified to be activated by voice commands and conversation, rather than AR or touch screen devices which can be difficult to navigate. Defining and programming configuration and manipulation of space is notoriously difficult, so by using neural networks which allows systems to “learn” without being explicitly being programmed would make it possible to continually output different configurations of space, where we
can quickly produce many different iterations and configurations of what a house might be.
