The company unveiled an ambitious plan in November 2000 that would have converted the top 27 floors of the building into 75 condominiums, including a five-story penthouse. The plan would have included a new residential lobby on Park Place, a 100-space garage, a 75-seat underground screening room, and a spa in the basement. The developers planned to spend $60 to $70 million on the conversion and to be ready for occupancy by August 2002. However, the Landmarks Preservation Commission opposed the plan because it would have required exterior changes to the roof. The commission eventually approved a version of the plan. Following the September 11 attacks, and the subsequent collapse of the nearby World Trade Center, the status of the plan was in doubt, and the proposal was later canceled.
