Foundations Underway for Alloy Block’s Second Phase at One Third Avenue in Downtown Brooklyn
At number 16 on our year-end countdown of the tallest construction projects in New York is One Third Avenue, a 725-foot-tall mixed-use skyscraper in Downtown Brooklyn‘s Alloy Block complex. Designed and developed by Alloy Development, the 63-story structure will yield 583 residential units, with 153 designated as permanently affordable. The project will also include 60,000 square feet of Class A office space and 30,000 square feet of retail. The structure is aiming for the title of tallest Passive House-engineered building in the world and will rise between State Street and Lafayette Avenue.
