Desert Submarine

This unique 241 square foot all solar design qualifies as a zero energy home. It’s for desert regions only. The home is cooled with water trickling over the metal roofing using the same evaporative cooling principle as found in the original Desert Submarine. It’s a simple yet proven technology. Solar panels power the water pumps, … Read more

Emergency Shelter Kits

Tim Merritt is working to provide emergency earthbag shelter in Haiti. He’s currently at the Haitian Academy, the site of the only full-time medical school in Haiti, not far from Port-au-Prince. The directors of the academy have offered land and are enthusiastic about building with earthbags. At this point, he’s getting set up with tools, … Read more

Barbed Wire Anchors for Seismic Regions

Cement mortar is inserted in some joints between bags to lock the barbed wire in place and increase tensile strength. Mortar isn’t needed between every bag, and most likely every course doesn’t need this extra reinforcement. Designers/engineers could strategically place the … Read more

Our roundhouse and dome are probably the two strongest buildings I’ve ever worked on. Our earthbag dome, for instance, never budged as about 15 truckloads of soil … Read more

That’s why I love thatch panels – they’re very inexpensive and all the tedious work has already been done. And they work great on round … Read more

Interior Walls

Using earthbags for interior walls would take up too much space and so they’re generally not recommended for this purpose. Thinner interior walls are more efficient. The easiest solution is to frame interior walls with 2x4s or, for plumbing walls, 2x6s. But there are more sustainable alternatives. On some of my plans I use adobe, … Read more
