Jay Shafer of Tumbleweed Houses designed the XS House. It’s one of their smallest designs at just 65 square feet.
Going this small has its benefits because the house is easy to park, tow, and maneuver. It also costs less than the other larger models, requires a less expensive trailer, and is easier to build and move.
