Supracollectives explores the possibility of designing collective forms of housing as extra-extra-large, multigenerational urban infrastructure. The studio reconsiders the megastructure as a cooperative, technologically advanced, and materially sustainable framework for co-living and working, examining not only the spatial logics of communal organization but also the relations between buildings, land-tenure regimes, environmentally viable modes of production and construction, and other forms of life and intelligence—animals, plants, emerging artificial actants—that increasingly shape contemporary urban environments. Within this framework, supracollectives names a radical amplification of the programmatic, technological, and ecological capacities historically associated with social housing, positioning it as a robust counter-narrative to neoliberal models of urban development.
