181 Fremont

181 Fremont is an 802ft 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.DesignThe slender mixed-use tower, developed initially by SKS Investments, is set to rise 700ft to the roof with 55 floors of offices and residential condominiums. A parapet/mechanical screen will reach to 745ft, and a spire will bring the total height to 802.5ft.The tower will contain 432000sqft of office space on the lower 34 floors (from 3 to 36), and 67 condominiums on the upper 15 floors (from 39 to 55). The 37th floor will contain residential amenities and a two-story open air terrace. Mechanical spaces would be on floors 2 and 38. The building will have a direct connection to the rooftop park atop the adjacent Transbay Transit Center from the fifth floor.Upon completion, the tower will be the tallest mixed-use building in San Francisco, surpassing the nearby Millennium Tower, and the 2nd-tallest in the Western United States. It would also be the second tallest building in the city after the Transamerica Pyramid. However, both are expected to be surpassed by the Salesforce Tower in 2017, making 181 Fremont the city's third tallest in the foreseeable future. 181 Fremont joins several other buildings designed to catalyze the San Francisco Transbay development area.
