Witkoff acquired 10 Hanover Square, located in Manhattan’s Financial District, in 1995. At the time, it was a 522,000 square foot office building. Following acquisition, Witkoff completed a gut renovation as part of an agreement to secure Goldman Sachs as a long-term tenant. When Goldman Sachs later vacated the building to move to their new corporate headquarters, Witkoff redeveloped the building into a 493-unit Class A rental building with ground floor retail and sold it to UDR, one of the largest national multi-family REITs.
