Cosanti is the gallery, studio and residence of Italian-American architect Paolo Soleri. Located in Paradise Valley, Arizona, USA and open to the public, Cosanti is marked by terraced landscaping and experimental earth-formed concrete structures.
Soleri is best known for Arcosanti, the prototypical arcological community founded in 1970 in the high desert, about seventy miles north of Phoenix, Arizona; that community still is comparatively remote. Cosanti is where Soleri and his late wife, Colly Soleri, had established their residence in metropolitan Phoenix in 1956, on a site (just a few miles from Taliesin West, where Soleri studied) which has since been surrounded by expensive suburban residences. Cosanti has been designated an Arizona Historic Site.
Paolo Soleri invented the words "Cosanti", "Arcosanti", and "arcology". He coined "arcology" by combining the words "architecture" and "ecology". "Cosanti" fuses two Italian words, "cosa" (which means "things") and "anti" ("against"). "Arcosanti" combines both "arcology" and "Cosanti".
