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.


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.


In 2007, SKS originally proposed 181 Fremont Street as a 66 floor, 900-foot (274 m) tall mixed-use skyscraper, with 140 residential units and 500,000 square feet (46,452 m2) of office space.[10] However, the developers reduced the height of the project to comply with the parcel's 700-foot (213 m) height limit, as detailed in the Transbay Center District Plan approved in 2012.[11] Still, this height limit is twice as high as the previous restriction.[12] The tower's design was approved in December 2012, and the development site was subsequently put on the market by SKS Investments.[13]

On March 29, 2013, Jay Paul Company announced that it acquired the development from SKS Investments and planned "to immediately commence construction" with completion expected in the second quarter of 2015.[14] According to Bloomberg, the building will cost US$375 million to construct, including land acquisition costs.[5] Demolition of the existing structures began in August 2013, with tower construction expected to begin in November.[15] Official groundbreaking ceremonies took place on November 12, 2013, and the 68 luxury residences were officially named Park 181.[7] Jay Paul Co. announced that the building would cost US$500 million to construct and is scheduled to open in early 2016.[7]
