Macklowe’s new office tower progresses

Developer Harry Macklowe might be preoccupied these days with settling billions of dollars in overdue debt and selling the GM Building. But he’s found time to keep a new project going. Macklowe secured a construction loan for $329 million from Deutsche Bank and Ullico for an office tower at 510 Madison Avenue and 53rd Street. The tower will feature a pool, golf simulator and rooftop deck. Asking rents are in the $135-plus range, and negotiations are ongoing for an anchor tenant and a restaurant. Asset management firm J. Goldman & Co. has agreed to leave the 26th floor of Carnegie Hall Tower for Macklowe’s tower.
