One Sansome Street, also known as Citigroup Center, is an office skyscraper located at the intersection of Sutter and Sansome Streets in the Financial District of San Francisco, California near Market Street. The 168 m (551 ft), 41 floor, 587,473 sq ft (54,578.0 m2) office tower was completed in 1984.
The One Sansome Street tower is built adjacent to the site of the ornate Anglo and London Paris National Bank, which was completed in 1910. Designed by architect Albert Pissis, the bank building was granite clad with 38 ft (12 m) high Doric columns. The historic architecture of the bank building serves as a conservatory for the skyscraper today.
One Sansome Street was acquired by Beacon Capital Partners LLC from BayernLB in 2005 for $217 million or $394.55 per ft² ($4,247.32 per m²). BayernLB bought the building in 1999 from subsidiaries of Citigroup and Dai-ichi Life Insurance Co. for between $170–175 million, or $310–320 per ft² ($3,337-3,445 per m²). By 2010, it was owned by Broadway Partners Fund Manager, LLC. In 2010, a partnership between Barker Pacific Group and Prudential Real Estate Investors took ownership of the building. In 2011, Citigroup signed a lease extension through 2022 to remain the building's anchor tenant.
The building contains direct underground access to the Montgomery Street Station.
