The 1.5 million-square-foot office and retail development at 666 Fifth Avenue has been the subject of a number of record-setting deals. Kushner Companies bought the property for $1.8 billion in 2007, at the time the most ever paid for a single office building in the U.S.

After the 2008 global financial crisis struck, in early 2010 Kushner's $1.215 billion loan was sent to special loan servicer LNR, in which Vornado Realty Trust would later take a stake. Kushner split the retail space into two condominiums, selling the smaller, 36,473-square-foot space to Inditex, parent company of fashion brand Zara, for $324 million or $8,300 per square foot on a blended basis, the highest price ever paid for commercial property larger than 10,000 square feet in New York City. Vornado bought a controlling 49.5 percent interest in the office condominium for $80 million in December 2011, and took the remaining 40,742-square-foot retail condo for $707 million in July 2012.

The 39-story 1957 building, designed by Carson & Lundin, stretches from 52nd Street to 53rd Street and includes landmarked lobby artwork: Isamu Noguchi's "Ceiling and Waterfall" installation.
