Projects Details

The 65-story 181 Fremont building is an 802 ft. mixed-use skyscraper in the south of market district of San Francisco, California. The tower contains office space on the lower 33 floors, and residential units and amenities including a two-story open air terrace on the upper 15 floors. The building has a direct connection to the rooftop park atop the adjacent Transbay Transit Center from the fifth floor.

The structure uses a traditional steelwork core for stability in conjunction with the mega frame design and moment frame perimeter steelwork.
