The world’s tallest Passive House building, a design standard aimed at cutting carbon emissions, is coming to Brooklyn. Alloy Development on Tuesday unveiled One Third Avenue, a 63-story mixed-use tower with 583 apartments, retail, and office space. Designed to be highly efficient, the project will complete the Alloy Block, a $500 million five-building development in Downtown Brooklyn with over 1,000 homes, the city’s first all-electric skyscraper, 60,000 square feet of office space, and two Passive House public schools.


One Third Avenue’s 583 apartments, including 152 affordable units, will be on floors 11 to 60. The tower includes a podium with six floors of office space. Plus, two historic buildings from the 19th century on State Street and Schermerhorn Street will be preserved and turned into retail.
The mixed-use tower will rise from an interior courtyard behind the two existing buildings. The residential lobby entrance will be in the State Street building and the commercial lobby entrance will sit on Schermerhorn and a public plaza. The site is conveniently near the Atlantic Terminal transit hub and the Barclays Center.


The building will feature oversized windows, an airtight, insulated building envelope, and filtered fresh air. Set to reach 725 feet tall, One Third Avenue will be the tallest Passive House-certified building in the world, surpassing the current record-holder, Vancouver’s 40-story Earth Tower.
“One Third Ave will raise the bar for sustainable urban development,” Alloy CEO Jared Della Valle said. “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.”
“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.”

Approved by the City Council in 2018, Alloy Block’s construction began in 2021. The development’s first phase included the 44-story tower 505 State Street, which runs fully on electricity. The building has 441 apartments, 45 of which are affordable, and amenities like a 3,000-square-foot gym, a yoga studio, a grow room, a rooftop pool, terraces, and 500 bike storage spots.
Leasing for the market-rate rentals began last year, priced from $3,475/month studios.
The development’s two Passive House-certified public schools opened last year. Designed by Architecture Research Office (ARO), the super-insulated building houses the Khalil Gibran International Academy, the nation’s first English-Arabic public high school, and the Elizabeth Jennings School for Bold Explorers (aka P.S. 456). As the city’s first Passive House public schools, the facility consumes less than a third of the energy of a typical New York City public school.
