An Elmhurst-based property owner has filed applications for a three-story, four-unit mixed-use building at 30-03 73rd Street, located on the corner of 30th Avenue in Jackson Heights. The project will measure 3,257 square feet. There will be 1,950 square feet of community facility space across the ground and cellar levels, followed by four residential units on the second and third floors. The apartments should average 814 square feet apiece. Midtown-based Prainito Design Group is the architect of record. The 4,000-square-foot lot is occupied by a two-story house. Demolition permits were filed in January.
