Long Island-based property owner Genara Gonzalez has filed applications for a four-story, six-unit mixed-use building at 842 Liberty Avenue, in northern East New York, located three blocks south of the Norwood Avenue stop on the J/Z trains. As proposed, the new building would measure just 3,203 square feet and include a 953 square-foot doctors office on the ground floor. The residential units would be extremely small, averaging 375 square feet apiece. But those plans could soon be replaced with a larger building, thanks to the proposed East New York rezoning. If approved, the site could accommodate a maximum of 3,600 square feet of commercial space and 5,400 square feet of residential space in the form of a four- to six-story building. Yonkers, N.Y.-based Leder-Luis Architectural Design is the architect of record. The 20-foot-wide lot is vacant.
