Less than a month after elevations were shared, the San Francisco Planning Department has published two new realistic renderings for the two-towered complex at 655 4th Street, across from the San Francisco Caltrain Station in SoMa. The details illustrations provide a glimpse at the prospective 435-foot complex that would create over a thousand rental apartments. Tishman Speyer is the project developer.
Solomon Cordwell Buenz is collaborating with IwamotoScott Architects for the design and Bionic for landscape architecture. The new renderings show familiar pixelated exterior skin along both towers, with corner balconies and a boxy rooftop terrace. The 12-story podium will feature a five-foot-deep gridded facade with metal and glass balcony railing, a rigid system that forms a visually strong foundation.
The most significant loss with the new plans will be the public space. The Bjarke Ingels Group-designed plan included a sheltered inner-block plaza accessible from three alleyways. The space would have included 19 retail spaces built around a landscaped plaza, a potentially attractive destination for pedestrians and residents alike. In contrast, the new ground-level contracts this accessible space to a corner park leading to the lobby and two of three retail spaces.
The 439-foot complex will contain just over a million square feet of residential area, with 418,680 square feet in the podium, 302,750 square feet in the shorter 402-foot tall 4th Street Tower, and 321,020 square feet in the taller Townsend Tower. An additional 9,850 square feet of retail will be created at street level. Parking will be included for 290 cars and 414 bicycles.
The complex will create around 1,105 rental units. Apartment sizes will vary, with 129 studios, 539 one-bedrooms, 400 two-bedrooms, and 37 three-bedrooms. All units will be priced as market-rate housing.
The 1.64-acre parcel is at the corner of 4th Street and Townsend Street, facing toward the San Francisco Caltrain Station. The new Fourth and Brannan Street light-rail platform is one block away, the last above-ground station before the new Central Subway connection to Union Square and Chinatown.
The project developer, Tishman Speyer, has been responsible for Mission Rock, a 28-acre masterplan for over a thousand homes, 1.4 million square feet of office space, retail, and public open space. Phase one of the master plan, which is nearly complete, includes the new global headquarters for Visa, a life sciences lab, and two residential towers.
City records show the property last sold in 2019 for $40 million. The estimated construction cost and timeline have yet to be revealed. Webcor Builders is listed as the general contractor in published development plans.
