Earthships are designed to behave as passive solar earth shelters made of both natural and upcycled materials such as earth-packed tires. Earthships may feature a variety of amenities and aesthetics, and are designed to withstand the extreme temperatures of a desert, managing to stay close to 70 °F (21 °C) regardless of outside weather conditions. Earthship communities were originally built in the desert of northern New Mexico, near the Rio Grande, and the style has spread to small pockets of communities around the globe, in some cases in spite of legal opposition to its construction and adoption.

Reynolds developed the Earthship design after moving to New Mexico and completing his degree in architecture, intending them to be "off-the-grid-ready" houses, with minimal reliance on public utilities and fossil fuels. They are constructed to use available natural resources, especially energy from the sun and rain water. They are designed with thermal mass construction and natural cross-ventilation to regulate indoor temperature, and the designs are intentionally uncomplicated and mainly single-story, so that people with little building knowledge can construct them. They can be perceived as a realization of the utopia of autonomous housing and sustainable living. thumb|Earthship windows, water barrels, and solar panels
