Linked to the future Transbay Transit Center via skybridge, 181 Fremont is distinguished by its angled top and diagonal bracing. Standing at approximately 700 ft. (802.5 ft., including the spire), the 60-story high-rise begins with five stories of lobby and retail, followed by 33 stories of Class A office space (435,000-sq.-ft.), one floor of amenities space, and 16 floors of exclusive condo residences (67 units). The project also includes five floors of subterranean parking with 192 spaces.

To support the structure, 44 caissons, 5-6 ft. in diameter, were driven an average of 262 ft. to bedrock. Post-construction, the project contains 20,000 cy of concrete, 1,287 tons of rebar and 14,272 tons of structural steel.

The urban infill project was constructed on a .35-acre parcel with a zero lot line, surrounded on three sides by other buildings and fronted by a highly trafficked street.

LEED Platinum pre-certified, the project includes a unique curtain wall system, recycled materials, 8% re-use of the demolished building that previously occupied the lot, and the City’s first gray water recycling system.
