The Phoenix model is larger than the basic Earthship option. It provides a roomy 5,000 square feet of living space. The overall shape of the Earthship is similar to a horseshoe. It features three bedrooms and two bathrooms. Although fireplaces are a luxury living item, some people enjoy the aesthetics of a fire on cold days, and the Phoenix has included one for this use.

One third of the entire area of the Phoenix model is designed for producing food. This option also consists of an aviary, fish pond, and a greenhouse.
