Tishman Speyer acquired the land for the project in 1999. The tower was originally approved by the Planning Commission on April 5, 2001 to rise and 30 stories. A revised plan, adding three stories and raising the height to, was approved on December 13, 2001. However, due to the downturn in the office market after the dot-com bust, developer Tishman Speyer froze the project waiting for economic conditions to improve. In 2006, five years after the building was approved for construction, work on the tower finally began. In January 2008, Tishman Speyer signed DLA Piper to occupy floors 22 to 26 of the tower. In March 2008, law firmGibson, Dunn & Crutcher agreed to take up of office space in the tower. In October 2009, Intellectual Property law firm Novak Druce + Quigg moved into the 34th floor penthouse of the building. As of summer 2008, close to half of the building's office space has been leased, with the possibility of more tenants moving in. In 2010, Deloitte signed a 15-year lease to occupy 10 floors of the building, becoming the anchor tenant, and taking up most of the remaining space. In June 2012, Tishman Speyer sold the building to Union Investment for US$446.5 million.
