Its supposed to be a high density alternative to sprawling cities. Its futuristic in concept and is meant to be a model development of sustainability. Arcosante is a test of design ideas. Problem is that there is no money for this development. Currently money is raised by the sale of wind chimes made in the complex, tours, retail sales, workshops, solari's other commissions, and from donors.
The real meat of the project, the two huge 40 or 50 story towers and all the functions to support those are in the vision but cannot be built due to funding. Supposevly 5000 people will live there
