Triple Island was located on Pier 42 in Lower Manhattan. It is a scalable and amphibious ecosystem that acts as a temporary habitat for residents. As a public experiment, Triple Island is an approach to living in a future New York replete with an acceleration of environmental challenges. We addressed the importance of decentralizing our basic resources by creating a regenerative living system that provides food, power, shelter, and water for its inhabitants from natural systems. We hope it can encourage community-based interdependent networks to further establish means of resource and skill sharing in our daily lives.
