Turtle Tuff Shelters builds affordable geodesic dome survival shelter kits. They are a bit more like tents than a full-time homes but seem like a potential alternative to a yurt. They come in two sizes, 16-foot and 24-foot, and cost between $1,200 and $3,400. The frame can be assembled in a couple hours by two people and weights between 200 and 450 pounds.
To keep the price low the sturdy cover material is not cut to fit a dome but is left rectangular instead. But once it’s all staked and tied down the covered steel frame structure can withstand 150 mile per hour winds. Also available is an insulation kit and an optional portable wood stove.
I don’t have any personal experience with this product, but it looks promising. Turtle Tuff Shelters is located in Orem, Utah.
