Developed by The Related Companies and AREA Property Partners (formerly known as Apollo Real Estate Advisors), its design by David Childs and Mustafa Kemal Abadan of Skidmore, Owings & Merrill, consists of two 750 feet (230 m) twin towers bridged by a multi-story atrium containing upscale retail shops. Construction began in November 2000, following the demolition of the New York Coliseum, and a topping-out ceremony was held on February 27, 2003. The property had the highest-listed market value in New York City, $1. 1 billion, in 2006.
