San Francisco, California

Located in California, between San Francisco’s SOMA and Potrero Hill, the 4-storey LEED-designed building is the city’s first cross-laminated timber structure. As part of the neighbourhood’s revitalization efforts, the mezzanine and ground floor incorporate light industrial uses with office space in the levels above. Following the industry shift towards green building, the developers chose wood for the iconic building to attract the sustainability-conscious tenants. A unique structural system composed of CLT slabs resting on notched glulam girders allows for a thinner floor composition by hiding the girder depth into the CLT slab. Glass curtainwalls enclose the unique, triangular-shaped structure to boldly showcase the exposed wood structure to passersby.
