Originally, Transbay Block 1 in San Francisco was zoned for development up to 300 feet. Builder Tishman Speyer wanted to go bigger. One hundred feet bigger, to be specific. In order to reach those new heights, the developer worked out a deal with San Francisco’s Board of Supervisors that increased the number of Below Market Rate (BMR) condos included in the project. With that, they got their approval.

Now, once the city deals with a few nearby projects, they’ll be able to break ground on their twisty, turny Folsom Bay Tower at 160 Folsom Street.

Designed by Studio Gang, the unique winding design will make the residential structure stand out in an already-crowded skyline. The design comes from the classic bay window, per the architect, which is an iconic feature in early San Francisco houses. As the design twists, the bay windows will always offer clear views, ample light, and provide texture to the exterior of the tower. The “visual noise” of the design is also meant to discourage birds from flying into the building.

The tower is set to include 391 total condos with 156 available at BMR. More than 10,200 square feet of retail space will front Folsom and Main streets while underground parking for 340 cars will sit underneath. The hope is to have everything ready so that residents can move in by the first quarter of 2020.
