Construction is rising on 100 Flatbush Avenue, a 44-story residential building in the Alloy Block multi-tower complex in Downtown Brooklyn. Designed and developed by Alloy Development, the 482-foot-tall tower will yield 441 residences with 45 units reserved for affordable housing. Urban Atelier Group is the contractor for the property, which is bound by Flatbush Avenue to the northeast, Third Avenue to the northwest, and State Street to the southwest.
Significant progress has occurred since our last update in June, when the reinforced concrete superstructure was just beginning to rise above street level. Now the building has reached the halfway mark and its glass curtain wall is quickly following the newly poured floors. The Flatiron-esque massing is clearly apparent when viewed from the southeast, as shown in the below photograph. Based on the pace of progress, the structure could top out in early 2023.
The following close-up shots show the details in the façade, which is composed of floor-to-ceiling windows and gray paneling arranged in tight vertical lines. Cladding Concepts is supplying the GFRC façade and rainscreen attchment system.
Meanwhile, the steel superstructures are progressing for the two grade schools included in the project. The Khallil Gibran International Academy High School at 380 Schermerhorn Street will have a cafeteria, a gymnasium, and a library; and an adjacent elementary school at 489 State Street will have a separate gymnasium and an auditorium accessible to the community.
The schools are designed by Architecture Research Office with Ismael Leyva Architects as the architect of record. Silman Associates and Magnussen Klemenic are the structural engineers, Cosentini & Associates is the MEP Engineer, Front Inc. is the façade consultant, Nelson Byrd Woltz is the landscape architect, Thornton Tomasetti is the sustainability consultant, Lighting Workshop is the lighting consultant, Langan is the geotechnical engineer, and AKRF is the civil engineer for the structures.
Below is a rendering showing the ground floor of the Khallil Gibran International Academy High School.
80 Flatbush Avenue, the cylindrical tower in the below rendering, is planned to rise behind the schools and cantilever over them. Work has yet to begin on this phase of construction, and it is unclear whether the rendering is still current.
100 Flatbush Avenue will become New York City’s building powered completely by electricity. These functions include the use of induction cooktops, heat pump dryers, hot water, and HVAC. Homes start on the third floor and go up to the 41st floor, and the majority of the residential amenities are expected to be housed within the multi-story podium. These include a fitness center, flexible workspace, and an outdoor rooftop swimming pool.
100 Flatbush Avenue and the two schools are planned to be completed in the first half of 2024, while the much taller component at 80 Flatbush Avenue is anticipated to take three years to build and will possibly be fully realized by 2027.
