Situated to the east of the Sherry Netherland, between Madison Avenue and Park Avenue, 520 Park Avenue, aka 45 East 60th Street, is now receiving its finishing touches. The 64-story and 781-foot-tall residential tower was designed by Robert A. M. Stern Architects, and contains 33 condominiums across nearly 178,000 square feet, averaging around 5,400 square feet apiece. The site sits in Lenox Hill on the Upper East Side, along East 60th Street. Zeckendorf Development, Park Sixty LLC, and Global Holdings Inc. are the developers while SLCE Architects serves as the architect of record. The skyscraper is the 21st-tallest tower currently under construction across the Five Boroughs, and the tallest on the Upper East Side.
