Salesforce Tower

Pelli Clarke Pelli Architects

 

Salesforce Tower is the tallest building in San Francisco, joining the Golden Gate Bridge and the Transamerica Building as one of the skyline's defining elements. Pelli Clarke Pelli Architects won an international competition in 2007 to design the tower and the Salesforce Transit Center at its base. Together, the two buildings represent a novel approach to public-private collaboration and sustainability in an urban setting.

The competition was sponsored by the Transbay Joint Powers Authority, a public entity created by the City of San Francisco to develop the new transit center. To help fund that building, part of the site was offered for sale to teams of developers and architects in an invited competition. Pelli Clarke Pelli Architects and its development partner submitted a design that focuses on sustainability, neighborhood development, and financial feasibility.

Standing 326 meters (1,070 feet) tall, Salesforce Tower has the simple, timeless form of the obelisk, giving the 61-story tower a slender, tapering silhouette. The walls are composed of clear glass with pearlescent metal accents. These horizontal and vertical accents gradually taper in depth to accentuate the curved glass corners. The walls rise past the top floor to form a transparent crown that appears to dissolve into the sky. Carved into the tower top is a vertical facet that features a public art installation by artist Jim Campbell, the tallest public art installation in the United States.
