The five-building Alloy Block master plan will encompass 850 units with 200 permanently affordable apartments, 100,000 square feet of Class A office space, 50,000 square feet of retail space, 500 parking spaces for bikes, two Passive House public schools designed by Architecture Research Office, and space for a local cultural institution.
100 Flatbush Avenue, a 44-story residential tower in the complex has been designed and developed by Alloy Development. The 482-foot-tall, fully electric-powered structure will yield 441 rental units. Of these, 45 will be dedicated to affordable housing. Residential units at 100 Flatbush Avenue will be equipped with induction cooktops, heat pump dryers, and base-building systems including hot water heaters and HVACs designed to make the structure carbon neutral. Homes will occupy floors three through 41 with most of the amenities housed within the multi-story podium. These include a fitness center, flexible workspaces, and an outdoor rooftop swimming pool. The retail space at Alloy Block will feature 20-foot-high ceiling spans that face Flatbush Avenue Extension.
The Khalil Gibran International Academy High School (KGIA) will feature a cafeteria, a gymnasium, and a library. A secondary elementary school at 489 State Street will feature a separate gymnasium and an auditorium accessible to the community. These public schools are the city’s first designed to meet Passive House standards.
Alloy also recently issued a Request for Proposals that seeks to partner with a community solar developer to enroll 100 Flatbush Avenue in projects that will secure a 100-percent local renewable energy supply for the building. The developer is the first to pursue such a program following a recent rule issuance by the New York City Department of Buildings around compliance with Local Law 97, which enabled developers to comply through off-site solar programs.
