New elevations have been published for the double-tower proposal at 655 4th Street in SoMa, San Francisco. The project is one of the largest in the city’s pipeline, aiming to create over a thousand apartments on 1.6 acres directly across from Caltrain’s San Francisco Station. Tishman Speyer, the same company behind the nearby Mission Rock master development, is the project sponsor.
The development will rise from the parcel with an L-shaped 11-story podium deck. The 4th Street Tower will rise 38 floors to a 405-foot pinnacle, while the Townsend Tower will rise 40 floors with a 435-foot peak. The project will create around 1.04 million square feet, with 1.03 million square feet for housing and 9,920 square feet for retail. Parking will be included for 408 bicycles and 284 cars. Three retail spaces will be created, two along Townsend Street and one along 4th Street.
Once complete, the building will create 1,105 homes across the podium and towers. Apartment sizes will vary, with 129 studios, 539 one-bedrooms, 400 two-bedrooms, and 37 three-bedrooms. Communal open space will be created with an expansive third-floor terrace space, two medium-sized setback terraces on the tenth floor, a podium-top terrace on the 13th floor, and two rooftop decks.
Solomon Cordwell Buenz and Iwamotoscott Architecture are jointly responsible for the architecture. The new illustrations show a pixelated rainscreen facade above the solid, dark metal-clad foundation. Elevations provide a glimpse into the prospective design but don’t reveal much about the three-dimensional massing. The most distinctive architectural feature revealed from the floor plans is the carved inner-lot corners of both towers. The articulated walls will create more corner window spaces and increase the distance to an average of 80 feet between the two towers.
The main lobby and two retail spaces will look onto the corner plaza designed by landscape architecture firm Bionic. The small plaza will feature built-in benches around raised planters. A large freeform planter will carve out a portion of the plaza, creating a direct path from the street to the residential lobby while giving the retail tenant along 4th Street a tree-shaded open space ideal for outdoor seating.
The 1.64-acre parcel is located along 4th Street between Townsend Street and Bluxome Street. Along with the Caltrain Station that 655 4th Street will overlook, future residents will be close to the Giant’s baseball stadium and their Mission Rock development.
The estimated construction cost and timeline have yet to be revealed. Webcor Builders is listed as the general contractor in published development plans.
