Facade Installation Underway for 345 4th Street, SoMa, San Francisco

Facade installation is nearly complete for a new seven-story mixed-use office building at 345 4th Street in SoMa, San Francisco. A recent site-visit by SFYIMBY shows that the curtain wall installation has reached the sixth floor, is fully installed along 4th Street, and nearly finishing along Tandang Sora Street. Stanton Architecture is responsible for the design and is listed as the property owners operating through 4th & Harrison SF, LLC.

The 85-foot structure will yield 53,890 square feet, with 49,900 square feet of office use and 2,670 square feet of ground-floor retail. Parking will be included for fifteen bicycles and no cars. Office workers will benefit from office-level balconies, a 2,670 square foot rooftop terrace with views of the city skyline, and 850 square feet of vegetation shaded by over a thousand square feet of solar panels. The building will also produce a newly landscaped alleyway connecting 4th Street and the residential Tandang Sora Street.
