This project proposes a pavilion space over Morningside Park Pond. The pond is the result of the buried history of the controversial Columbia Gym that was proposed in 1968. The gym was heavily protested for its aggressive land acquisition of community space by Columbia as well as the segregated spaces it proposed. The site for the gym was excavated, but the project was abandoned, leaving behind it the space the modern-day pond would occupy. The pavilion unearths this buried history by mimicking but changing the materiality of the proposed gym with the mesh, creating a space of gathering, teaching and researching through various interfaces with the skin. Leveraging the unique ecosystem of pond, the “ghost” of the gym which once proposed to segregate becomes a multispecies community center.
