An anonymous Long Island-based LLC has filed applications for a four-story, seven-unit residential building at 102-12 Radcliff Avenue, in Corona. The project would measure 6,770 square feet and its residential units should average 711 square feet apiece, indicative of rental apartments. Gino Longo’s College Point-based firm is the architect of record. The 2,500-square-foot lot is occupied by a single-story house. Permits indicate demolition began on the structure last week.
