The image of the living cell on which it was based encompasses notions of growth, division, exchange, transformation, autonomy of parts, deconstruction, recycling, rings and dynamic stability.1 The goal was to create architecture that would change, grow and metabolize and would encourage the par- ticipation of those who used its products. Me- tabolism devoted a great deal of energy to the topic of technology and human beings and is often thought of mistakenly as a technological movement, but according to Kurokawa, its fundamental concept was in fact symbiosis.2 Architecture and the city were seen as open Fig. 2.

The movement addressed the relation- ship of cities to natural systems, buildings to the city and building components to the build- ings. They were at once interdependent and autonomous. With the idea of autonomy of the individual came the expression of capsule ar- chitecture where each individual living unit has an independent identity. Capsule architecture was not intended for mass production but was instead intended as deconstructed architecture and sought to create a plurality of new possi- bilities of combination.7 The inherent modular- ity of the capsule concept lent itself to prefab- rication and started a wave of interest and re- search into prefabricated modular housing ion Japan in the 1960s and 1970s. METABOLISM REVISITED 249 In the US, the perception of affordability in prefabricated buildings has come with the negative perception of inferior quality. Accord- ing to Dwell magazine “the manufactured housing industry is stigmatized.” The Dwell home design invitational, an international de- sign competition to design an affordable prefab home, has championed the image of prefab housing by producing reasonably priced pre- fabricated houses skillfully designed in con- temporary styles. Dwell’s mission was not only to design affordable houses but also to pro- mote the image of prefabrication and modern architecture.8 Perceptions of prefabrication, however, may be culturally related and vary from place to place. In Japan for example, pre- fabricated housing has been the norm for nearly a generation. There is a sense that pre- fabricated homes are modern and well suited to contemporary lifestyles. As Japanese people are also very fond of their automobiles, one clever advertising campaign showed a man who had just finished washing his car turn the hose on his waterproof vinyl house to wash it as part of his weekend ritual. This is perhaps indicative of a move in Japan, away from the extended family structure towards the nuclear family where the house, like the automobile, is viewed more as a commodity than a perma- nent structure to serve a family for genera- tions. With the increasing mobility and imper- Fig. 3.
