Haim Levy’s Jamaica-based Phoenix Home Realty Inc. has filed applications for a four-story, four-unit residential building at 526 Kosciuszko Street, in Bedford-Stuyvesant, located two blocks west of the Kosciuszko Street stop on the J train. The new 4,520 square-foot building will rise on a vacant 20-foot-wide lot and will boast full-floor apartment units averaging 1,087 square feet apiece, indicative of condominiums. The same developer is also expanding the adjacent three-story townhouse at 528 Kosciuszko Street. That building will be expanded to 3,692 square feet (a growth of 374 square feet) and will contain three full-floor residential units. Apartments at 528 Kosciuszko will average 1,231 square feet apiece. Queens-based Gerald Caliendo is the architect of record.
