Brooklyn’s tallest tower has some serious competition in the works. Ava DoBro topped out earlier this year at 595 feet, but a tower nearly twice its size may be brewing for a lot just a block from the residential high rise, Crain’s reports.

Developer Michael Stern — he of the 1,400-foot-tall (and we mean tall) tower rising at 111 West 57th Street on Manhattan’s Billionaires’ Row — just made a $90,000,000 deal with developer pal Joe Chetrit of Chetrit Group to purchase the former Dime Savings Bank of New York at 9 Dekalb Avenue. The building is lovely. But no one thinks that Stern and Chetrit are in it for the classical architecture.

Buying the building comes with 300,000 square feet of air rights which would enable the duo to build a 600,000 square foot tower on an adjacent site they co-own at 340 Flatbush Avenue Extension, according to Crain’s. The building could be the city’s first to rise taller than 1,000 feet outside of Manhattan.

Brownstoner took the above photo just this morning, and added CityRealty‘s rendering of the possible new construction to show how very towering the tower may be.
