An Earthship is a brand of passive solar earth shelter that is made of both natural and upcycled materials such as earth-packed tires, pioneered by architect Michael Reynolds.

Earthships are predicated upon the idea that there are six human needs which can be addressed through environmentally sustainable building design:

  1. Energy: Thermal and/or solar heating and cooling, solar and wind electricity
  2. Garbage Management: Reuse and recycling built into construction and daily living
  3. Sewage Treatment: Self-contained sewage treatment and water recycling
  4. Shelter: Building with natural and recycled materials
  5. Clean Water: Water harvesting and long term storage
  6. Food: In-home organic food production capability

Earthship structures are intended to be “off-the-grid-ready” homes, with minimal reliance on public utilities and fossil fuels. They are constructed to use available natural resources, especially energy from the sun and rainwater.

  • They are designed with thermal mass construction and natural cross-ventilation to regulate indoor temperature.
  • The designs are intentionally uncomplicated and mainly single-story so that people with little building knowledge can construct them.
