ONE community responds to demographic diversity, proposing various living conditions while maintaining a cohesive community. Melrose, South Bronx, is very diverse in household composition, languages spoken, and age—both senior housings and public schools populate a lot here. However, the neighborhood lacks safe street life for kids and senior citizens. We tried to address the issue by varying living choices and outdoor space in different scales and levels while maintaining community cohesiveness. Our design approach started from two completely different living conditions—a tower and a plinth. The differences are coordinated under the continuous surface from the tower’s south facade to the plinth’s roof. Under the consistency lies various unit choices, from a townhouse to a co-living cluster, from a single studio to a double-height unit. Shared programs are subtracted from the mass to provide accessible outdoor space for all of the units within their diameter. Despite the high density on-site, a wide range of community life parallels domestic life.
