The Hexayurt Project:
The Hexayurt is a new kind of sheltering solution. To make the simplest hexayurt, make a wall by putting six sheets of plywood on their sides in a hexagon. Cut six more sheets in half diagonally, and screw them together into a shallow cone. Lift with a large group on to the wall, and fasten with more screws. This shelter will last for several years and costs less than $100. It may be ideal for a variety of disaster relief situations.
