Treasure Island

San Francisco, CA

Treasure Island sits in the heart of San Francisco Bay with the new Bay Bridge serving as a dramatic backdrop – an extraordinary location that will soon be home to one of the most transit-oriented sustainable developments in the country. Rising on the site of this former naval station will be a new San Francisco community comprised of two distinct and vibrant neighborhoods with up to 8,000 homes (single family townhomes to mid-rise and high-rise towers, including 25% designated as affordable housing), three hotels, mixed-use space for retail and commercial ventures and vast stretches of public parks and open spaces laced with walking and bike trails. Plans for a new ferry quay and terminal will provide direct access to and from San Francisco. While much of the island is a blank canvas, several buildings are listed in the National Registry of Historic Places, and will be rejuvenated with great care.

In the midst of the design process, we decided to rotate the grid 35 degrees to orient streets and buildings southerly. We want to warm homes and parks with as much direct sunlight as possible while minimizing wind channels.

Local History

A man-made treasure from the very beginning.

Treasure Island is a man-made landform built in 1936-37 to host the 1939 Golden Gate Exposition. It became a US Naval Station in 1942. Throughout World War II it housed helicopters, sea plans and airships in its hangars, and served as a processing center for 12,000 men a day deployed to the Pacific arena. The US Department of Defense closed the base as part of its downsizing efforts in the 1990s. Since then it has served as a spectacular setting for filmmakers and festival-goers. In 2011, the San Francisco Board of Supervisors approved the 20-year development of the site.
