NEW YORK CITY — SL Green Realty Corp. has announced plans to redevelop One Madison Avenue, a Class A office tower in the Midtown South neighborhood of Manhattan. The adaptive-reuse project will involve reducing the existing building to its ninth floor and building 18 additional stories above. When completed, the building will span nearly 1.5 million square feet. The addition will feature modern office space and tenant specialty floors as well as more than an acre of outdoor terraces. Demolition and construction are expected to start in 2020 following the expiration of existing tenant leases. A design and development team of Kohn Pedersen Fox, Hines and Gensler has been selected for the project.
