An anonymous Brooklyn-based LLC has filed applications for a five-story, six-unit residential building at 137 Carlton Avenue, located in Fort Greene. The project will measure 10,181 square feet and its residential units should average 1,132 square feet apiece, indicative of condominiums. Many of the apartments will span two floors, with no single unit taking up an entire floor. Midtown South-based Murat Mutlu Architect is the architect of record. The 2,925-square-foot lot is occupied by a single-story commercial building. Demolition permits have not been filed.
