It’s been more than a year since the New York City Housing Development Corp. authorized funding for a massive overhaul of the YWCA on Atlantic Avenue between Nevins and 3rd Avenue, and the renovation is in full swing. The entire building is being revamped and, when complete, will contain 84 new studio rental apartments on the lower floors. The timeline for the project was two years, according to a representative for HDC, which puts the expected completion date at late this year or early next year. The studios will range from 250 to 300 square feet and marketing for the units will begin six months before the project is complete. The apartments will all go to low-income women through a lottery. The upper levels of the building will continue to have SRO units, and those rooms are also being renovated. GMAP
