The Suspended City Skyscraper, from American designers Coolie Calihan and Charles Johnson, focuses on the creation of urban density, sustainability and diversity in Rio de Janeiro.
The Suspended City (Cidade Suspensa) uses an enormous suspension system (hence the name) to create a dense urban waterfront development that exists almost entirely off the ground. Designed to minimize the building footprint in areas where land is limited, two pylons support a framework that reaches out over the ocean, forming an elegant curving structure.
Emphasizing both self-sufficiency, the Suspended City is divided into several layers including separate areas for living, green space, commerce, energy generation, waste recycling and food production. The design concept utilizes biomass generators for electricity generation. Additional green features include wastewater treatment and purification, and intensive farming of vegetables, fruit and fish for food sustainability and security.
The Suspended City received a Special Mention in the eVolo’s 2010 Skyscraper Competition.
