Major Urban Tech Campus Proposed in Bustling Central SoMa

New, 9 comments

A full SoMa block that now houses a parking garage and auto repair shop will be transformed by developer Boston Properties into an urban campus, most likely for tech. The developer, which is also behind the Salesforce Tower, has submitted a proposal for a 1.1 million-square-foot building at Fourth and Harrison streets, right across from the SoMa Whole Foods. The building is in the heart of Central SoMa, where plans for increased height limits have sparked an explosion of development proposals, including ones at the Flower Mart and the SF Tennis Club.

The new Boston Properties proposal has a more distinctive design that most other new buildings, with a carved 240-foot tower designed by HOK that rises out of a 65-foot podium. There would also be a 130-foot tall midrise tower. Boston Properties and HOK previously teamed up on 535 Mission, the glassy SoMa tower that now wears real estate website Trulia's logo on its exterior.

The biggest challenge for the proposed complex could be Proposition M, the cap on new office space that can be added to San Francisco each year. Room under the cap is scarce, especially with all the new development proposals on the table, meaning this development's proposed 907,300 square feet of space dedicated to office usage could come up against the cap's limits.
