Gavin Harkness developed a design for a shelter made out of four polyiso panels that is simple to build. It's intended as a 2 people hexayurt, made from 4 sheets of 8x4, and can be built with as little as 4 cuts.
It stands 1.2m high, 2.4m long and just under 2.1m wide.
There are 8 pieces: 2 roof pieces and 6 wall pieces:
- Two end panels and one side panel (that's three pieces) are cut from a single sheet. Do that twice.
- The roof, in its simplest form, doesn't require any cutting at all. You can use a tape hinge at the top.
