Flanked by the Caltrain station and I-280 freeway off-ramp, 510 Townsend sits at a vital gateway to San Francisco. The area—which has long been populated by light industrial and warehouse buildings—is undergoing a transformation as the demand for office space with character grows alongside the city’s need for housing. The entire building is leased to a notable tech company.
The building is stepped to respond to the differing neighborhood scales and contexts; the prominent Townsend Street elevation is 7 stories while a more modest 5 story height faces out onto Harriet Street. The brick façade, black mullions, and small glass windowpanes are inspired by neighboring historic buildings. Windows are set in to create visual depth and provide solar shading. A through-block pedestrian path encourages the community to take a “short cut” through the site and enjoy a landscaped mini-plaza with a significant public art installation.
The 20,000 sf roof deck features an urban garden and 360 degree skyline views. The sloped roof meets height requirements while creating a seventh floor mezzanine. The building’s side core allows for a 6 story atrium with a winding stair.
