San Francisco, 2013
CitySpace-SoMa is a demonstration project which seeks to test the potential of high performance, net zero energy, factory-built dwellings in dense urban environments. Working with Panoramic Interests (developer), and Zeta Communities (prefab builder), Trachtenberg Architects helped to refine the 350 sq. ft. prototype which Panoramic and Zeta were in the process of developing in a factory and developed the architectural design for this 23 unit, four-story building.
While Zeta Communities had successfully built one and two story single family dwellings this was their first large multi-family project and the first higher than two stories. The 23 units were fully built-out in a factory in Sacramento (including all cabinets, finishes, fixtures, and lighting) and trucked to San Francisco. The four-story building was erected over the course of just four days on a tight South of Market alleyway site.
The project received a LEED Platinum rating and includes many innovative sustainable features including rainwater harvesting, solar hot water heating.
