A nonprofit affiliated with the Archdiocese of New York has revealed plans to build a new, all-affordable apartment complex on the Lower East Side.

The Grand Street Guild will build two 15-story towers, one specifically for seniors and the other for families and individuals. The group has hired New York’s Handel Architects, the same firm behind San Francisco’s sinking Millennium Tower, to design the project.

Local blog The Lo-Down reported that District Leader and Grand Street Guild resident Paez said one of the towers will be built on the site of a parking garage at Broome and Clinton Streets, and the other will be replace a Broome Street daycare, one block over. Both sites are just a block south of the Williamsburg Bridge on-ramp. The complex is being built in collaboration with New York City’s Housing Preservation and Development and the city’s Housing Development Corporation, along with U.S. Department of Housing and Urban Development.

Grand Street Guild has built and maintained affordable housing in the neighborhood for decades. In 1973, the organization build three towers with 600 units on the land surrounding St. Mary’s Church on nearby Grand Street. This time, there will be 400-plus rental units total, and construction is slated to begin in the summer of 2019.

The project will rise amid Essex Crossing, the massive mixed-use development at Essex and Delancey streets whose first phase will wrap in 2018.
