An empty lot on the Grand Concourse that was once home to a historic school will be transformed into an affordable housing complex.

P.S. 31 was once known as the "Castle on the Concourse," but was torn down in 2015 as it hadn't been in use since the 1990s. City officials stated it was structurally unsound, beyond repair and unsafe.

The Department of Housing Preservation and Development says a mixed-use 24-story affordable housing complex will be built in the lot, along with a charter school, supermarket and medical services.

Ed Garcia Conde says he's been in direct opposition with the city before and after the demolition, and that he was frustrated over the removal of the landmark designation by the Landmark Preservation Commission.

The Department of Housing Preservation and Development tells News 12 significant parts of the building will be a part of the new structure, including gargoyles, some archways and select stonework.

Officials say the affordable development is scheduled to close on financing next week.
