Planning

The development is planned for a triangular plot in Brooklyn. One of the buildings on the site, a former Civil War infirmary, will be preserved and re-purposed as a cultural facility. The completion of the project was contingent on the rezoning of the site owned by Alloy and the New York City Department of Education so that two towers can be built and floor-area ratio can be tripled. Without the rezoning, Alloy would still be able to build a single tower taller than the

Construction and changes

As of October 2019, demolition of the site's preexisting structures had begun. The first tower, designated as 100 Flatbush Avenue, was supposed to have been built by 2022, and the second tower would have been completed by 2025. Alloy announced in December 2019 that the first tower would be the first fully-electric mixed-use skyscraper in New York City; the first tower was pushed back to 2023 and the second tower was delayed to 2026. The project was delayed significantly due to the

. In May 2021, Alloy announced that, due to a steep decline in office space during the pandemic, the office space at 100 Flatbush Avenue would be scrapped. The number of apartments at 100 Flatbush would increase from 257 to 441. By the middle of that year, the project had received a construction loan of $240 million, allowing work on the project to commence. The development was renamed the Alloy Block. Work on the first tower's foundation started in December 2021. The
