Roosevelt Island is a long sliver between Manhattan’s Upper East Side and the rapidly developing eastern Queens waterfront. The residential tower was one of the first buildings constructed for the Cornell Tech campus, which was established with a multipurpose academic research building. While Cornell Tech is situated at the center of the most densely populated city in the United States, the campus is physically isolated from both Manhattan and Queens, with limited public transportation. Instilling a sense of community among faculty and students was important both for launching the new campus academically and for making living on the island attractive. We used the ACUHO’s Project for 21st Century Academic Housing to design nesting levels of social interaction throughout the residential building. The 26-story residential tower is stacked into thirteen two-story blocks that form “neighborhoods” connected by double-height common rooms. The ground floor has a lounge and fitness center. There are a large meeting room, roof deck, and outdoor terraces for socializing.
