NYC’s first Passive House public schools open in Downtown Brooklyn

New York City's first Passive House-certified public schools have opened in Downtown Brooklyn, setting the bar for sustainable education. Designed by Architecture Research Office (ARO), the ultra-low-energy-use building houses two schools: 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). Part of the mixed-use development Alloy Block, the facility consumes less than a third of the energy of a typical NYC public school.

New York City's first all-electric skyscraper launched a housing lottery on Tuesday for 45 mixed-income apartments. The 44-story residential tower in Downtown Brooklyn, previously 100 Flatbush Avenue and now called 505 State Street, will run totally off electricity instead of natural gas and apartments will have sustainable features. New Yorkers earning 40, 60, and 100 percent of the area median income can apply for the apartments, which include studios ranging from $763 to $2,017/month, one-bedrooms from $812 to $2,155/month, two-bedrooms from $965 to $1,502/month, and three-bedrooms from $1,105 to 1,725/month.

Construction set to begin on five-building Alloy Block development in Downtown Brooklyn

By Devin Gannon

After securing $240 million in financing, Alloy Development announced construction will kick off this month on its huge mixed-use, multi-building project in Downtown Brooklyn. Formerly known as 80 Flatbush, Alloy Block includes five buildings with 850 apartments, 200,000 square feet of office space, 40,000 square feet of retail, and two public schools designed to meet Passive House standards. Since first announcing the project roughly four years ago, developers have cut the height of the residential towers, swapped out planned office space for additional residences, and pushed back the expected completion date.

City Council approves 80 Flatbush development in Downtown Brooklyn

By Devin Gannon

The New York City Council voted on Wednesday to approve 80 Flatbush, a five-building mixed-use development planned for Downtown Brooklyn, Curbed NY reported. The approval comes after negotiations last week between Alloy Development and Council Member Stephen Levin, who represents the area, which led to a shorter, less-dense complex. After the developers agreed to cut the height of two buildings, one from 986 feet to 840 feet and another from 560 to 510 feet, the Council's subcommittee on zoning voted in favor of the project.

NYC Council committee approves 80 Flatbush project in Downtown Brooklyn after height chop

By Devin Gannon

The New York City Council's subcommittee on zoning voted unanimously Thursday to approve the rezoning application that allows for the construction of 80 Flatbush, a five-building complex planned for Downtown Brooklyn. Following negotiations between Alloy Development and Council Member Stephen Levin, the developers agreed to cut the height of two buildings, one from 986 to 840 feet and another from 560 to 510 feet (h/t Brooklyn Paper). New renderings reveal not only smaller buildings but an updated design as well. With this key approval, the project will most likely get support from the full City Council followed by Mayor Bill de Blasio.

986-foot Flatbush Avenue tower in Downtown Brooklyn gets revised renderings

By Devin Gannon

Ahead of its public review, Alloy Development this week released new details and renderings of its proposed mixed-use development at 80 Flatbush Avenue in Downtown Brooklyn. Developers amended the complex's design, first released in April, following backlash from the community and more than 100 meetings with local stakeholders. While the taller tower will keep its original design with 74 stories, the 38-story building's profile will be slimmed and feature a masonry facade to complement the neighboring Williamsburgh Savings Bank Tower.

Alloy Development announced plans to build a pair of towers at 80 Flatbush Avenue, a 61,000-square-foot parcel of land between Flatbush Avenue, Schermerhorn Street, Third Avenue and State Street. The developer–who, with the Department of Education, owns the land–has been selected by the city’s Educational Construction Fund to build the mixed-use complex as part of the redevelopment of the Khalil Gibran International Academy, which will move into one of the two new school buildings that will be part of the project. The second of the two will be a 350-seat elementary school. The project will also offer 900 apartments (200 of which will be affordable), a 15,000-square-foot cultural facility, 200,000 square feet of office space and 40,000 square feet of retail space.
