The design for 270 Brannan recreates a sense of the lost topography of the historic site, echoing back to the historic Rincon Hill by providing a lower entrance on Brannan Street along with a higher entrance at the end of De Boom Street. The resulting mass of 270 Brannan ends up as two blocks stepping up the hill, one for each street exposure, organized around a central covered court. The court serves as the organizational and social heart of the building and is covered by a suspended steel and glass canopy incorporating natural ventilation for the space. The facades along Brannan and De Boom integrate with the “bricky” historic character of the neighborhood, but with contemporary materials and detailing, notably using a terra cotta rain screen with subtly different colors and aluminum curtain wall in the higher floors of the building. The Building tenants will enjoy ample daylight, flexible floor plates and a large roof deck, all offering views of the neighborhood and the bay beyond.
