Commercial Union Assurance Building, Renaissance Revival office building with roof terrace in the Financial District, San Francisco, United States.
This 16-story structure rises 94 meters high and features symmetrical facades adorned with classical limestone and terracotta details, exemplifying early 20th-century Renaissance Revival architectural style.
Completed in 1921 by architect George W. Kelham, the building was constructed during the post-World War I economic growth period and matched the height of San Francisco City Hall at that time.
The building represents San Francisco's architectural evolution and serves as a testament to the development of the American financial sector during the prosperity era of the 1920s.
Located at 315 Montgomery Street, the building operates Monday through Friday from 9:00 AM to 5:00 PM and currently houses modern office spaces and flexible coworking areas.
Its roof terrace provides panoramic city views while maintaining the original Renaissance Revival architecture with decorative cornices and classical proportions throughout the structure.
