I present to you NOAH.. the New Orleans Arcology Habitat (Arcology meaning architecture and ecology)...
the purpose of NOAH is to combine large scale structures of sustainability with urban design .. basically creating a self sufficient city...
The structure designed and proposed by Kevin Schopfer (Ahearn Schopfer Architects) would be composed of 30 million sq ft that will house all the aspects of society needed to be socially self sufficient:
20,000 units of housing
1,500 time share units
500,000 sq ft for retail
8,000 parking spots
