Tucson Mountain House The Tucson Mountain House, located outside of Tucson, Arizona in the Sonoran Desert was designed by Rick Joy and completed in 2001. Due to the drastically changing temperatures between the daytime and nighttime, the house is made with 2’ thick rammed earth walls to regulate the temperature of the house, absorbing the heat and keeping it cool during the day, and releasing the heat into the house during the cold nights. Located on a gently rolling desert site with a variety of cacti and sagebrush, the Tucson Mountain House is the ultimate home for relaxation and enjoying the views and landscape.
