6th Holcim Awards 2020/21

138 Cities like Quito have uncountable underused flat rooftops that can be transformed to become a strategic resource for urban densification. The project proposes the installation of housing modules to inhabit the unoccupied roofs of existing buildings in a form of urban commensalism. Juxtaposing an extra layer over an existing construction, the strategy is sustainable across many facets: avoiding land speculation and urban sprawl, using existing facilities and infrastructure – thereby offering significant potential for financial savings – and providing affordable housing opportunities for the population. Despite the minimalist approach underlying the project, the prototype is designed to be modified and customized to adapt to different users’ needs. The structure is made of unprocessed wood with interior walls in plywood and an exterior metal cladding.
