Jared developed a design for a shelter made out of two polyiso panels that has just enough space for sleeping and nothing more. A shelter made out of two 48x96 inch walls and a 48x96 inch floor of some other material produces an equilateral prism with cut ends that is 41 inches high - larger in every dimension than most single person tents.
You start with two panels, each of them 4 foot by 8 foot. In each panel, cut (by cutting the diagonals) two rectangle triangles, each 4 feet (the short side of the rectangular panel) by say 2 feet. You now have 4 triangles and 2 isosceles trapezoids (like here). Change the orientation of the triangles along the diagonals, and there you have it. (Harder to explain it than to see it.)
Obviously polyiso is a bad material for the floor, so Jared's next step is to look into semi-rigid plastic sheets. A tarp with wood boards at each end is another option or even a sheet of plywood. His plan is to make it [Camp_Danger_Hexayurt_Hinge_Technique semi-folding], and install a small swamp cooler at one end and a furnace filter in the other.
It's been suggested it's best not to have a floor for the Playa, as the ground acts as a heat sink.
If the height is 41 inches, a 6' person can sit on the floor.
Good for naps. "Siestayurt" anyone?
