Immersed in a world of sustainable farming and ecovillages, I would sometimes hear hints and faint glimpses of a mysterious “urban laboratory” located just two hours north of Phoenix, Arizona. This unique concrete jungle-gym is currently home to about 70 residents who are carrying on the legacy of Paolo Soleri, a famous architect who designed Arcosanti and began construction in 1970. The intention of the project is to provide a model that can demonstrate Soleri’s concept of “Arcology”, architecture coherent with ecology. Arcology was envisioned by Soleri as a hyper-dense city, designed to: maximize human interaction with ready access to shared, cost-effective infrastructural services; conserve water and reduce sewage; minimize the use of energy, raw materials and land; reduce waste and environmental pollution; increase interaction with the surrounding natural environment. There are day tours all day long of this center and also rooms for rent on Airbnb. This is my story of Convergence at Arcosanti, a conference-festival hybrid that I hope I see much more.
