181 Fremont Street is an 802 ft (244 m) mixed-use skyscraper under construction in the South of Market District of San Francisco,California. The building, designed by Heller Manus Architects, will be located adjacent to the Transbay Transit Center and 199 Fremont Street developments.

181 FREMONT STREET, SAN FRANCISCO, CA 94105

The slender mixed-use tower, developed initially by SKS Investments, is set to rise 700 ft (210 m) to the roof with 54 floors of offices and residential condominiums. A parapet/mechanical screen will reach to 745 ft (227 m), and a spire will bring the total height to 802.5 ft (244.6 m).

The tower will contain 411,000 sq ft (38,200 m²) of office space on the lower 33 floors (from 3 to 35), and 68 condominiums on the upper 15 floors (from 38 to 52). The 36th floor will contain residential amenities and a two-story open air terrace. Mechanical spaces would be on floors 2, 37, 53 and 54. The building will have a direct connection to the rooftop park atop the adjacent Transbay Transit Center from the fifth floor.^[8][9]

Upon completion, the tower will be the tallest mixed-use building in San Francisco, surpassing the nearby Millennium Tower, and the tallest in the Western United States.^[7] If completed by 2016, it will be the second tallest building in the city, after the Transamerica Pyramid. However, it is expected to be surpassed by the Transbay Tower in 2017, making it the city’s third tallest in the foreseeable future. 181 Fremont joins several other buildings designed to catalyze the San Francisco Transbay development area.

Located in the heart of San Francisco, this building is one of several developments that will change the San Francisco skyline. Heller Manus’ unique 54 story design features innovative building technologies and structural systems. The lower 36 levels will feature Class A office space while the upper 15 levels will feature 68 market rate and below market rate residential units. The project features on-site amenities and direct access to the Transbay Park which is adjacent to the tower.

Watry Design was brought on board after learning that the complex Transbay Terminal shoring system impacted this site’s original stack lift parking design. After studying several options including conventional self-parking, mechanical lifts, and automated robotic valet, the project is pursuing an all valet scheme with automobile elevators to access the below grade levels. There are 150 valet parked spaces in 4 basement levels.

This project will pursue LEED Platinum certification by incorporating innovative curtain wall systems, a green roof, and energy efficient mechanical systems. 

Parking supports:

• 54 story, type 1 tower
• 400,000 square feet of office
• 68 residential market rate & BMR units
