A controversial plan to boost the coffers of the financially-strapped Brooklyn Public Library system with the revenue from a new condo tower is moving forward.

Last fall, library trustees approved the $52 million sale of the system’s Brooklyn Heights branch to the Hudson Companies which planned to build a new market-rate condo tower on the coveted site. As part of the deal, the developer would also include a new library within the tower and commit to building 114 units of affordable housing off-site. The local community board has now signed-off on the plan, which sends it to the Brooklyn Borough President’s office and then onto the City Planning Commission, reported the New York Times.

The Hudson Companies has tapped Marvel Architects to design all aspects of the project including the condo tower, new library branch, and the two affordable housing buildings that will rise in Clinton Hill a couple of miles away. (During construction, the developer will also set up an interim library near the existing branch.)

The triangular-shaped, 36-story condo tower is clad in limestone and has dark spandrels bands that cut across its skin. The new public library is housed in the building’s base, facing Borough Hall and the stately court buildings across the street. On the structure’s Clinton Street–facing side, there is space for a lobby, two retail outlets, and a connection to the below-grade community space.

The two affordable buildings included in this project have a notably more austere presence, both with boxy brick facades and significant setbacks. The units in these buildings will be available to those making between 60 and 165 percent of the Area Median Income.

Brooklyn Public Library president and CEO Linda E. Johnson told the New York Times that $40 million from the sale will go toward four other struggling branches in the borough. It’s a significant figure, especially for the system which has $300 million in unmet capital needs.

The project could break ground in 2016.
