Excavation is moving along at 570 Fifth Avenue, the site of a 32-story commercial skyscraper on the eastern edge of the Diamond District in Midtown, Manhattan. Designed by Kohn Pedersen Fox and developed by Extell, the 567-foot-tall structure will yield nearly 1.1 million square feet, with the majority devoted to Class A office space. The project will also contain retail space on floors one and two, an 80,000-square-foot flagship store for IKEA on the first two cellar levels, as well as a gym, swimming pool, basketball court, and juice bar on the third and fourth below-grade stories. The development is located between West 46th and 47th Streets.
