San Francisco, CA (August 12, 2018) Pelli Clarke Pelli Architects unveils the 1.2 million square foot Salesforce Transit Center including its rooftop park, Salesforce Park. Stretching four blocks along Mission Street, one block south of the city’s Financial District, the long awaited Transit Center is a new paradigm for urban design in the United States.Pelli Clarke Pelli’s architectural design illustrates how a dense, urban, transit-based development can provide a sustainable and livable city. In the future, the Transit Center will link to eleven transit systems, high-speed rail, connecting the city to the region, the state, and the nation.

Brilliant, Innovative Design

Salesforce Transit Center draws together local, regional, and national transit networks into a soaring, light-filled building. The light column is the centerpiece of the Grand Hall which is both supporting the building and bringing daylight into its core, creating a welcoming urban space. Reaching from the park, down through the bus deck and Grand Hall to the train platforms two stories below grade for anticipated Caltrain and high-speed rail, this dramatic structure provides light and views to all areas of the Transit Center.

Outside, visible from afar and floating above the street, is a gently undulating wall-inspired by the “Penrose Tiling” invented by famed mathematical physicist Sir Roger Penrose. The wall is both a veil and an enclosure creating a light cloud-like structure visible from many vantage points in the city. At street level, shops and cafes will draw visitors and energize the neighborhood.

Roof Top Park

At the heart of the Salesforce Transit Center is the 5.4-acre public rooftop park, known as Salesforce Park. The lushly landscaped park features gathering spaces, places for quiet repose and a sprawling lawn with a 800-person-capacity natural amphitheater. Also woven into the landscape is a restaurant and a children’s playground.  Multiple entry points, including bridges that connect to surrounding and future buildings, welcome visitors.  The dense flora offers a wide variety of Bay Area ecologies, from redwood trees to a wetland marsh.


The roof top park is symbolic of Pelli Clarke Pelli Architects and Salesforce Transit Center’s commitment to environmental quality and sustainability. With more than 600 trees and 16,000 plants, the ecosystem will capture 12 tons of carbon annually.

The Transit Center will also reduce greenhouse gas emissions significantly.   The  annual energy consumption is projected to be 50 percent lower than the 2008 Title 24 Energy Efficiency Standards. Its associated carbon emissions will be reduced by approximately 40 percent.

The Transit Center’s roof, by virtue of having the park, retains and reuses storm water that would otherwise flow into sewers. The building’s water reuse system is among the first of its kind in San Francisco. It is also the first project in San Francisco with a rooftop wetland filtration system.  This will save 13.9 million gallons of water and 17,000 tons of carbon dioxide each year due to water conservation and reuse.

The project is on track to receive a Gold certification under the LEED 2009 rating system.

Art Meets Architecture

The Transbay Joint Powers Authority, the public agency charged with implementing the Transit Center project, commissioned four major artworks that have been integrated with the Transit Center’s design. Working in collaboration, Pelli Clarke Pelli Architects and the artists have blurred the lines between art and architecture, making both more accessible to the general public. The stunning visual art elements include:

White Light by Jenny Holzer

Parallel Light Fields by James Carpenter

Bus Fountain by Ned Khan
