How To Build an Earthbag Roundhouse
Building with earthbags or sandbags, depending on where you are from is both old and new. Sandbags have long been used, and still are to this day, particularly by the military, for creating strong, protective barriers, or for flood control. The same reasons that make them useful for these applications carry over to creating housing. Since the walls are so substantial, they resist all kinds of severe weather even bullets and also stand up to natural calamities such as earthquakes and floods.
They can be erected simply and quickly with readily available components, for very little money. You can build homes, storm shelters and root cellars using this method. Did you know to cut costs even more you can buy just the bags and fill them with sand or dirt from your property. This would pretty much half the cost of your project, maybe more.
