The "Pup Hexayurt" is a small structure made from a single sheet of 1:2 material (usually insulation foamboard, like the large hexayurts). Cutting the sheet into four equal rectangles, there is enough to create the needed roof triangles and all wall panels but one. Useful for sheltering equipment and supplies.

If you change the cut pattern a little, you can get six walls 4/5ths of a square high.
Here’s how:
Cut the board two, along the long axis, giving you two 2′ x 8′ pieces.
Cut one of those pieces into five identical rectangles.
Cut the other as described to give you the triangles, plus a square, which you trim down into the sixth rectangle.
Not *quite* as elegant as the five wall because it produces some wastage, but workable.
