First of its Kind

The building was one-of-a-kind in SOMA when it was built in 1988 and  paved the way for other developers to see the potential of the district. 100 First Street is now at the center of some of the city’s most ambitious developments, including the Transbay Transit Center, a $4.5 billion project with a regional transit hub and Salesforce Tower, the centerpiece of the San Francisco Transbay redevelopment plan.
