“…the Earthship is the epitome of sustainable design and construction. No part of sustainable living has been ignored in this ingenious building.”
~ Michael Reynolds
Earthships are self-sustaining all the way down to the primary design of the building. Each dwelling creates its own electricity, water catchment, a contained sewage treatment system, and production of food. Owning an Earthship can help reduce or eliminate utility bills by:
The main systems that allow this to happen are heating and cooling, electricity generation, collection and treatment of sewage, building materials, water, and food production. While there are detailed explanations of each on our systems page, here is a brief overview:

The Nautilus model has a strong and elegant shape. Its design is based on a Fibonacci sequence. This particular sequence features numbers calculated by adding the previous two numbers. This creates an evenly spaced shape in the form of a nautilus or snail. This model uses rammed earth walls made out of tires, just like other models. However, the walls of the Nautilus model are also enclosed in straw bales.
The Nautilus gets its name due to its spiral shaped floor plan. The layout wraps around a bedroom loft featuring a fireplace. The opposite bend of the spiral shape plan is made into a cistern for water storage.
The Hut model contains circular rooms when built using rammed earth walls made out of tires. The roof is a manufactured steel rebar. It is bent and wired together. Afterwards it is sheathed in a mesh made of wires and placed at its destination on top of the tire walls before using cement to plaster over it.
The Hybrid model is a mixture of both the bedrooms of the Hut model and the Packaged model, which helps provide an easier ability to expand. Plus it offers a double greenhouse to significantly increase the food production.
The Hybrid can be used in either hot or cold wet climates. This model is able to be modified for handling large amounts of snow, such as the amounts Colorado Springs receives, without deviating from the basic layout. The Hybrid cannot modify either its north or south faces. However, the east or west areas can be changed to the length desired by the owner of the building.
One of the oldest Earthship layouts is the Global model. Each time the Global model is constructed, we learn from it. Then, using the lessons from each building, we create better methods and options for the design and construction of future models. The Global design allows it to function off the grid no matter what climate the building is in. This makes it a great choice for Colorado and the 300 days of sun per year we have here.
In this model, a network of cooling tubes under the earth, and convection skylights, work simultaneously to supply the dwelling with natural air conditioning and aeration. The Global model has been built in a variety of places around the world including: Canada, Holland, Mexico, Turkey, and the United States.
The Global Earthship model is easy to change and most Global models are built by the Earthship staff within a few months.
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.
There are endless possibilities for the design and manufacturing of a custom built Earthship. Unlike other Earthship design options, a custom-built Earthship option is designed for individual preferences and not for optimum performance. However, a custom Earthship is worth the effort if you know what you want.
