9 DeKalb Avenue

The residential tower planned for 9 DeKalb Avenue will top out at 1,066 feet to become the tallest building in Brooklyn.

9 DeKalb Avenue (originally referred to as 340 Flatbush Avenue Extension) is an under-construction supertall residential skyscraper in Downtown Brooklyn, New York City by Michael Stern’s JDS Development Group.[1][4][5] When completed it will become the tallest structure in New York City outside Manhattan, as well as the first supertall building in Brooklyn.

Designed by SHoP Architects, 9 DeKalb Avenue marks the third collaboration between the firm and high-end developer JDS Development Group after the American Copper Buildings and the super-slender 111 West 57th Street – known as “111W57” – on Billionaires Row.

Unlike the world’s thinnest skyscraper, which due to its small footprint was only able to offer luxury high-end residences, 9 DeKalb Avenue will include retail and office space as well as a commercial gym alongside 575 apartments, 20% of which will be affordable rentals.

Incorporating the historic Dime Savings Bank into its podium, 9 DeKalb Avenue’s unusual shape nods to the bank’s hexagonal floorplate.
