Bronx-based Blue Water Development Group has filed applications for a three-story, five-unit residential building at 422 Leland Avenue, located in the Classon Point section of the East Bronx. The project will measure 5,568 square feet and its residential units should average a family-sized 906 square feet apiece. Great Neck, N.Y.-based AM/PM Design & Consulting is the architect of record. The 3,750-square-foot site is occupied by a single-story house. Demolition permits were filed last December.
