Challenge / Description

One Sansome St. sits atop a base that includes portions of a historic building that once housed the Anglo & London Paris National Bank. The building is named Citigroup Center at One Sansome - after the bank that built the tower in 1983 to house its West Coast operations. Citibank, who currently occupies 122,000 sq. ft. of space in the building, renewed its lease with BPG in 2011.

Upon acquisition by Barker Pacific Group and Prudential Real Estate Investors, the occupancy had fallen to 75% and common areas needed refurbishing. The BPG and Prudential joint venture has invested over $75 million to upgrade the building. The capital improvements include: new ceiling and lighting in the main lobby, new security console, new elevator cab interior finishes and lighting, and installation of multiple furniture and carpet arrangements in the lobby. The building is currently 100% leased with 54 tenants.
