ARCA is a housing construction system designed to make gentle density both feasible and compelling by rethinking how housing is built – combining architectural precision, material innovation, and contextual design. ARCA’s pilot project is situated on a standard R1 lot in Los Angeles’s Playa del Rey neighborhood – a vacant parcel that embodies both the challenges and opportunities of low-density zoning.
