What if we rethought the power of housing design beyond the provision of living units on an architectural scale? In | On | It is a proposal at the urban scale for a sustainable intergenerational living community that metabolizes over time. An urban community network is designed as the foundation of housing, through the reclamation of vacant lots and adaptive reuse of storage units transforming derelict and inaccessible waterfront land into a new public destination. The design prioritizes connectivity and accessibility from the rest of the Bronx to the new waterfront through a hierarchy of negatively carved spaces, extending Grand Concourse as a primary public pedestrian ‘artery’ disintegrating into semi-public secondary porous ‘veins’ and semi-private ‘capillaries’ within each interior floor. Co-living housing builds upon the cohesion of communities established through the connective urban realm.
