Urban Infill
Architecture and design work on building within existing urban fabric, including small lots, gap sites, stacked housing and extensions to dense neighborhoods.
Urban infill refers to the design of new buildings on vacant or underused plots within established cities. Architects working on infill must respond to tight boundaries, neighboring structures, limited daylight and constrained access, which shapes both massing and construction methods.
Members here share projects that address these constraints, from narrow townhouse gaps and corner lots to stacked modular homes and extensions that wrap around existing trees or courtyards. The work also includes compact hospitality and prefabricated approaches suited to difficult sites.
