Building Types & Designs


Self-sustaining, can be totally off-grid, modern homes constructed from locally-sourced, reclaimed materials. Earthships can be built in any part of the world, in any climate and still provide comfort, electricity, potable water, contained sewage treatment and sustainable food production.

Passive House

The passive house design is ultra-insulated, sealed tight and can have some or all earthship systems: electricity, potable water, contained sewage treatment and sustainable food production.

Custom (Green & Conventional)

Conventional building layouts using sustainable materials and system. Looks like a conventional home, but acts like an earthship. Can include some or all of the earthship systems: electricity, potable water, contained sewage treatment and sustainable food production. Craftsman designs, Colonial designs, Standard American Homes designs an more.


  • Off-grid with grid-intertie for both power and water. One or All of these systems can be added to any kind of building. All designs and building types can include some or all of these systems:
    catch water
    sustainable food production
    greywater planters
    contained sewage treatment planters


Green building

Green building is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building’s life-cycle from siting to design, construction, operation, maintenance, renovation and deconstruction. This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building is also known as a sustainable or high performance building.

Some practices, such as using local and renewable materials or passive solar design, date back millennia, The Anasazi in the Southwest built entire villages so that all the homes received solar heat in the winter. The contemporary green building movement arose out of the need and desire for more energy efficient and environmentally friendly building practices. The oil price increases of the 1970s spurred significant research and activity to improve energy efficiency and find renewable energy sources. This, combined with the environmental movement of the 1960s and 1970s, led to the earliest experiments with contemporary green building.
