Sky City in Changsha, China, will be 2750 feet tall, 220 stories, housing 30,000 people in 4450 apartments, with excavation and construction slated to begin in June, 2013.
Aiming to accommodate a growing population, the skyscraper is considered a "pragmatic" building, designed for efficiency, affordability, replicability.
The Sky City concept significantly reduces the per capita use of land, and the associated CO2 emissions generated, thus providing a means of large-scale development with a significantly lower impact on the environment.
As a result, a resident of Sky City will be using 1/100th the average land per person- learn more about this innovative building concept and its sustainable features at Treehugger.
