What Is The Cosanti Foundation?

Arcosanti Is a Project of The Cosanti Foundation

Founded in 1965, The Cosanti Foundation is an Arizona-based 501(c)(3) nonprofit organization.

Our mission is to inspire a reimagined urbanism that builds resilient and equitable communities sustainably integrated with the natural world.
Our vision is a world of equitable communities which improve earth/life balance and do better with less.

We pursue this mission and vision at our two flagship locations, Cosanti (in Paradise Valley near Phoenix) and Arcosanti (near Mayer in central Arizona), as well as with projects, programs, and partnerships that hundreds of thousands of people have participated in over the last 57 years.

The word “cosanti” is a combination of the Italians words “cosa” (meaning “things”) and “anti” (meaning “against” or “before”). It signifies The Cosanti Foundation’s commitment to a way of living, working, and building that is oriented away from consumption and materialism, and is respectful of our planet’s natural rhythms and resources. Through ongoing experimentation with and application of the principles of arcology (a combination of the words architecture and ecology), we seek to demonstrate a kind of construction and community that offers an alternative to sprawl development and a solution to modern social and environmental crises.

The Cosanti Foundation also owns and operates the for-profit Cosanti Originals, where we make our world-famous bronze and ceramic windbells and other artisan items.

How We Work

Over the last 60 years, The Cosanti Foundation has developed an extensive set of educational programs that help to increase public understanding of arcology. Through hands-on workshops, lectures, publications, academic partnerships, cultural collaborations, festivals, conferences, and tours of the experimental architecture at both Cosanti and Arcosanti, The Cosanti Foundation has reached millions of people all over the world, and continues to reach and teach hundreds of thousands of people every year.


Cosanti and Arcosanti were built by hand by more than 8000 students and volunteers who came from all over the world to participate in our signature multi-week workshop program. That program continues today, but with an emphasis on maintaining and utilizing a prototype arcology and urban laboratory, rather than merely building one. Graduates of this program are considered our alumni.


The four central tenets described below are our core areas of advocacy, and have guided our work from the beginning.

Read Taylor's Bio

In his fifth year thesis, Taylor explored a theme of borders between manmade human habitation and the natural environment: borders of access for residents to view and value the earth, and borders to prevent encroachment while stimulating urban density.

Working at Arcosanti has given him a rare opportunity to explore aspects of urbanism and environmental protection not typically offered in mainstream industry. He seeks to learn through helping others learn in a growing city of people with a village-mentality of work and relationships.
