Prefabrication experiments - 171 - Geometries - 02 - Capsules and megastructures


Directing the efficacies of regular geometric principles to housing helped initiate a class of technical architecture formed by modular building blocks, volumes and prefabricated containers amassed to breed homes and even cities. Illustrated in a diversity of patterns throughout the 20th century but most notably by Japanese metabolists, Kisho Kurokawa posited and tested a simple equation, unit+unit+unit…=city, exploring multiple tessellations for an architecture based on unitary coherence. 

Japan’s massive post war reconstruction efforts paralleled by government support for industrial development certainly played an important role in establishing these patterns for building adaptable and reconfigurable architectures based on a simple mass produced capsules. Described most characteristically for the Nagakin Capsule Tower (1970) but also explored for the Capsule Village (1972) and for the Concrete Capsule House (1975), the capsules were designed as complete technological liveable containers to be plugged into a shared infrastructure or megastructure. Each megastructure was designed as a base and conduit for implanting or detaching prefabricated boxes as the city grew or needs evolved. 

The Capsule Village designed to receive leisure dwellings in a plug and play pod format was perhaps the purest expression of the metabolist vision. A large-scale three-dimensional truss spanned intermediately placed concrete supports charting a steep topography outlining a field of potential dwelling outlets. The dancing megastructure touching the landscape sporadically presented the idea of minimal site disturbance further informing its potential to be constructed or deconstructed as needed. The «homo movens» (the mobile man) zeitgeist was central to the development of this type of evolving structure. 

The tubular space frame was the chassis for attaching circulation elements, ductwork for piping and power lines distributing services to containers affixed to the space frame by mechanical and reversible joints. Each capsule of monocoque construction measured 3 meters by 6 meters was organized according to three dwelling functions: hygiene, eating and sleeping. The mechanical box like aesthetic exemplifies the designer's fascination with space age imagery. Present in both the capsule tower and the Capsule Village the simple rectangular geometry associated with dwelling reduced the home to a no frills functional unit, a type of micro architecture that integrated home and furniture into an ergonomic whole.
