The document proposes renovating and expanding an existing building on Governors Island to serve as a Marine Academic and Science Technology (MAST) center for The Harbor School. The design focuses on integrating the building with its waterfront location, encouraging habitat, and being environmentally conscious. Key aspects include cantilevering floors over the water, adding an intensive green roof, and designing spaces to utilize rainwater and reduce energy costs. The project is proposed to be completed in three phases to renovate existing structures, expand the waterfront, and fully realize the design.
