The high school faces the more active Flatbush Avenue intersection.

The building houses PS 456, a New York City public primary school, and Khalil Gibran International Academy, an Arabic language public high school. The Flatbush project is a part of Alloy Development’s The Alloy Block, a mixed-use development in Downtown Brooklyn. This community-oriented project includes units of mixed-income housing, office space, retail space, and a new cultural facility in a preserved historic structure.

The smaller scale new primary school, PS 456, opens onto a brownstone-lined street while the Khalil Gibran International Academy’s larger scale is situated on Flatbush Avenue, a major thoroughfare with large scale commercial, cultural and residential development. It is located near Atlantic Terminal, the Brooklyn Cultural District, and Barclays Center.

The gymnatorium double functions as both a gym and gathering space.

The existing high school will have a new and expanded state-of-the-art home and increased school capacity for students. It will share facilities – such as a new cafeteria, gymnasium, and library – with the new public primary school.
