Challenge

Situated in the rapidly changing South of Market (SoMA) neighborhood of San Francisco, the last remaining development site at the Transbay Terminal was acquired by TMG Partners and Northwood Investors in a complex transaction structure involving a lender, disputed owner, and bankruptcy court. The parcels were zoned as part of the Transit Center District Plan in conjunction with the new Transbay Transit Center. The site has 225,000 square feet of existing buildings, which will be renovated while TMG finalizes entitlements and approvals for almost 2 million square feet of mixed-use development.

Solution

Planned and designed by Foster + Partners in collaboration with Heller Manus Architects, the mixed-use skyscraper complex consists of two towers with 1.35 million square feet of office space and 650,000 square feet of residential units. Responsive in urban and environmental terms, the sustainable development brings together places to live and work with the city’s key transport hub. At ground level, the buildings provide a new publicly accessible urban space, and new pedestrian routes through the site will knit the proposed design with the urban grain of the city.

Impact

The San Francisco Planning Commission noted in their approvals that “the Project will generate substantial revenues that will contribute to the development of transportation infrastructure, including the Downtown Rail Extension, and other improvements envisioned by the Transit Center Plan.” It will also “add employment and housing opportunities within a walkable urban context,” while “employees and residents would be able to walk or utilize transit to commute and satisfy convenience needs without reliance on the private automobile. This pedestrian traffic will activate the sidewalks and open space areas in the vicinity.”
