The San Francisco Transbay Center, home to the world's largest rooftop park and a unique transit and recreation center, is the jewel in the crown of one of America's most exciting cities. Developed in collaboration with the team at Pelli Clarke & Partners, we redesigned the Transbay Terminal to change the way people connect, enhance the city's biodiversity, health, and economic sustainability.

From Concept to Execution

The Transbay terminal redevelopment was one of the most significant architectural competitions to be held. On September 20th, 2007, the TJPA competition panel announced that we had won the competition in favor of Skidmore Owens & Merril and Richard Rogers.

We partnered on this massive project with architecture office Pelli Clarke & Partners from conceptualization to design, presentation, and visualization.

Finally, the world will see that a rooftop park can become so much more than a few potted plants. The concept of a proper ecologically-designed space, providing spatial quality, health benefits, economic value, and strengthening biodiversity could be realized.

Salesforce San Francisco Transbay Center features innovations such as water and air purification, ecosystem services, biodiversity boosters to provide a cleaner environment and an exhilarating new green space in the city. Enhancing the health, wildlife, and sustainability of the region is key to this example of progressive urban renewal.

Bus services began operating from here in 2017, and the park officially opened in 2019.

Celebrating Innovation

The Transbay competition was designed to seek a unique and functional replacement of the old transportation hub on the same site and create an iconic tower for San Francisco.

The environmental concerns were considerable, the development time short, and the stakes high. Pelli Clarke & Partners hired Except to conceptualize and jointly develop the environmentally-driven design.

With Atelier Ten, our environmental engineering partner, the Transbay design culminated in a globally unique proposition. Except were involved in core concept generation, roof park development, including the ecological system, water features, and funiculars/gondolas. Likewise, we also helped produce the main square, bridge connections, and park landscape design.

In 2017 the project was renamed 'Salesforce Park' in a long-term sponsorship agreement with the Salesforce company, including the nearby 'Salesforce Tower'.
