Extell Development Company is an American real estate developer of residential, commercial, retail, hospitality, and mixed-use properties. Founded in 1989 by Gary Barnett, the company’s portfolio exceeds 20 million square feet.[1] The company has between 125 and 150 employees.[2] Prior to 2005, it was known as Intell Management and Investment.[3]
In a 2013 survey conducted by The Real Deal, Extell was the most active builder in Manhattan, with at least 11 active projects totalling over five million square feet.[2][4]
In the early 2010s, Extell used financing from Abu Dhabi's sovereign wealth funds to build One57, the first "Supertall" residential skyscraper in Midtown Manhattan, which kickstarted the creation of the "Billionaires' Row," a series of super-tall condo towers below Central Park.
