Alloy shares renderings of One Third Avenue, phase two of Downtown Brooklyn’s Alloy Block megadevelopment

The future, 63-story building will go up at the intersection of 3rd Avenue, Schermerhorn Street, and Flatbush Avenue. It will be tucked behind two historic buildings from the 1800s, a new passive house school by Architecture Research Office (ARO), and another, albeit shorter 44-story tower at Alloy Block—New York’s first passive skyscraper.

    One Third Avenue will rise 725 feet, making it just over 200 feet taller than its iconic neighbor, the Williamsburgh Savings Bank Tower by Halsey, McCormack & Helmer. “One Third Ave will raise the bar for sustainable urban development,” Alloy CEO Jared Della Valle said in a statement.
    “Developing a Passive House building at this scale will be incredibly challenging, but the payoff will be significant with high quality living that remains environmentally friendly and energy efficient,” Della Valle added. “The second phase of the Alloy Block will demonstrate new possibilities to the industry and stand as an example of a solution that helps stall climate change.”

There will be a total 583 apartments at One Third Avenue. Of those, 152 will be affordable; those flats will be between floors 11 and 60, Alloy said. The architects will simultaneously reuse two historic 19th-century buildings which are on the site today on the corner of State and Schermerhorn Streets. Those buildings will be converted into retail.

    The podium level of One Third Avenue will rise six floors and have office space. This portion will be elevated 100 feet above grade, and have a total 11,300 square feet of leasable area per floor.
The facade of One Third Avenue will be orthogonal and square, not unlike the supertall by Rafael Viñoly in Midtown Manhattan. The facade by Alloy however will have a darker hue, and the oversized windows will be 6 feet by 7.5 feet, while still adhering to Passive House standards, architects said.
