Extell Development

Extell Development Company is a privately held real estate developer founded in 1989 by Gary Barnett and headquartered in Midtown Manhattan. The firm operates as a fully integrated platform spanning site acquisition, capitalization, design/construction oversight, sales/leasing, and ongoing property management across residential, hospitality, office, retail, and mixed-use projects. Its strategy is best characterized as “trophy-asset” development in high-barrier, high-liquidity locations—primarily New York City—supplemented by selective expansion into resort and adjacent metro markets where Extell can control large-scale sites and create mixed-use destinations.

Extell’s portfolio emphasis skews heavily toward luxury residential (condominiums and high-end rentals) and mixed-use towers that pair housing with destination retail and/or hotel components.
