Fareri Associates is planning to develop a three-million square-foot biotechnology research complex on roughly 80 acres of undeveloped land adjacent to the Westchester Medical Center and New York Medical College, in Valhalla. Dubbed the Westchester BioScience & Technology Center, it will, once complete, include 2,252,600 square feet of research facilities, 400,000 square feet of medical offices, and a 34,000 square-foot Children’s Living Science Center. In addition, a 100,000 square-foot hotel with 100 rooms and 114,000 square feet of ground-level retail are planned. The project will be built in phases and is being designed by Torti Gallas & Partners. Of the 80 acres of land, 43.6 acres of land will be preserved as green space. The developer must first lease roughly 60 acres of land from Westchester County, according to Westfair.
