through the many things that Cal-Earth offers to the community and the world.

Cal-Earth, The California Institute of Earth Art and Architecture,

is a 501(C)3 non-profit/charitable foundation at the cutting edge of Earth and Ceramic Architecture technologies today. Founded in 1986 by its director, Nader Khalili (1936-2008), its scope spans technical innovations published by NASA for lunar and Martian construction, to housing design and development for the world's homeless for the United Nations.

Continuing in his tradition, Khalili's associates and apprentices are dedicated to research and education of the public in environmentally oriented arts and architecture. Its philosophy is based on the equilibrium of the natural elements of earth, water, air, fire, and their Unity at the service of the arts and humanity.

Cal-Earth's mission is guided by three principles: (1) shelter is a basic human right, (2) every human being should be able to build a house for him or herself, and (3) the best way to provide shelter for the exponentially increasing human population is by building with earth.
