An Earthbag Round House For Less Than $5,000
Looking for a very stable design which does not only come cheap from the start but also makes you save money in the long run. Due to its shape and materials used, the earthbag house has less area than your normal home, so it’s cheaper to keep it supplied with energy. Don’t be scared if you never built circular structures before, because the example shown here used a technique called the compass arm which you can easily learn. Recycled or salvaged materials were used wherever it was possible, like in the door or on the floor. The tutorial has photos showcasing almost each step of the building process so if you decide to replicate the project, use it to help and guide you along the way. At the end you will have the comfort of 450 ft² with less than $5,000 spent overall.
Starting on the rubble trench foundation. Railroad ballast was used for the rubble.
Covering over our sediment fabric with pea gravel.
Two rows of stem wall – 80 lb sack concrete. 2 strands of barbed wire go between every row. The thing in the middle is our building compass, made from chain link parts, used to keep the walls round and level.
Earthbag Building is the first comprehensive guide to all the tools, tricks, and techniques for building with bags filled with earth—or earthbags.
A similar method is “Superadobe”. Cal-Earth (nonprofit organization) provides hands-on methods of learning how to build Superadobe structures… Superadobe (sandbag and barbed wire) technology is a large, long adobe. It is a simple adobe, an instant and flexible line generator. It uses the materials of war for peaceful ends, integrating traditional earth architecture with contemporary global safety requirements.
