About 400 Howard St

The new glass mid-rise office building located at 400 Howard Street is part of a complex of four architecturally-linked buildings known as Foundry Square. Foundry Square I is situated on the northernmost corner of the Square in San Francisco’s desirable South of Market District. Completed in 2007, this ten-story building has 336,699 square feet of Class A office and retail space to rent.

The building was designed specifically to accommodate technology firms, and therefore has large floor plates for trading or other contiguous operations, attractive open meeting spaces and a reliable emergency power supply. Ceiling heights are 11’ from floor to ceiling, and natural light abounds due to the building’s beautiful glass walls. Office space is currently 97% leased to BlackRock.

Retail space offers tenants maximum flexibility, and is delivered in vanilla shell condition. ADA bathrooms are part of all retail units. Notable retail tenants include Specialties, Spice Kit, and Peets.

Adjacent to the Transbay Terminal, tenants have excellent access to BART/Muni lines. Car commuters will enjoy ease of access to the 80, 280 and 101 highways. The building enjoys a prime location close to FiDi in San Francisco’s hot SoMa submarket.

The dramatic glass façade with stone accents mirrors and complements its sister buildings on each of four corners. Each building has an entry plaza facing out onto the common intersection, creating a large, attractive public open space in this bustling area. Foundry Square I’s plaza features a 40 foot stainless steel sculpture called “Time Signature,” by Richard Deutsch.
