This booklet is the second in a twelve part series that walks the owner/builder through the construction of a Global Model Earthship. This installment covers the concrete and steel strength of the building, including footings, buttresses and bond beam. Photographs, diagrams and thorough explanations of procedures will guide you through the concrete work phase of the building. <br><br>With over 40 years of experience, Michael Reynolds has developed a 'living' home that heats and cools itself passively, harvests/treats/ and reuses its water four times, collects its own electricity, and grows its own food. The Global Model, which incorporates the double greenhouse, is the culmination of years of experimenting and building with recycled materials. These booklets have been put together with input from the Earthship crew, who have built hundreds of these homes around the world.
