Foundry Square

Foundry Square is a complex of four architecturally-linked, 10-story mid-rise buildings located at Howard and First Streets near the Transbay Terminal in the South of Market neighborhood of San Francisco, California. Each of the four buildings stands on a different corner of the street.

The project's first phase, Foundry Square II (405 Howard Street) and Foundry Square IV (500 Howard Street), was completed in 2003. Each building is a mixed-use structure. The total interior area is 1,200,000 square feet (110,000 m2). The design team included STUDIOS Architecture, Jim Jennings Architecture, Page & Turnbull, Webcor Builders, and landscape architect SWA Group. The developer was Wilson Equity Office (now Wilson Meany Sullivan). Current tenants include the law firm of Orrick, Herrington & Sutcliffe, Uber and the headquarters of Gymboree.

The third building, Foundry Square I (400 Howard Street), was completed in 2007. In April 2012, Tishman Speyer acquired the entitlements to the final building, Foundry Square III (505 Howard Street), from Wilson Meany Sullivan, and broke ground later that year. Foundry Square III is expected to be completed by the end of 2013 or beginning of 2014.

A unique feature of the site was SWA Group's concept for using each of the 1,000 square feet (93 m2) contained within Foundry Square's four open corners to form a larger, unified public square. Each building's 200-foot (61 m) dual-glaze glass walls frame the square, establishing an arcade that defines the transition between interior building space and public exterior spaces. The four corners of the intersection are integrated by the use of public art and sculpture (such as Richard Deutsch's "Time Signature" stainless steel sculpture), tree bosques, ground-floor cafes, and over-scaled pots. The project earned SWA Group the ASLA Northern California Chapter Merit Award in 2006.
