Architect Paolo Soleri was born in Turin, Italy, in 1919. He settled permanently in Arizona in 1956 and almost immediately began to build Cosanti, his home and studio near Scottsdale, as an experiment in eco-friendly habitation. Fourteen years later, Soleri launched Arcosanti, his low-impact city in the desert, 65 miles north of Phoenix.
