Description: Many readers prefer rounded domes. However, rounded domes cannot be built by earthbags alone. This solution — inspired by Richard Laurens — uses a 24′ diameter geodesic frame set on 42″ high earthbag walls. Metal and wood geodesic frames are available as kits through various suppliers, or you could build your own. Lightweight bags of insulation cover the entire dome. A key feature is the expansive window wall that provides a sunny, pleasant home. Most dome homes, in contrast, have insufficient or poorly protected windows.
