Cut out 12 rectangles of a 1:2 proportion.
Cut six of them across the diagonal for the roof to be compiled into 6 isosceles triangles.
Stick the triangles together to for a conical structure for the top.
Attach the remaining 6 rectangles to each other using tape. When you are done, you should have a flimsy 6 sided figure that can be manipulated to look like a hexagon.
The top of each rectangle would be of the same length as each isosceles triangle.
Therefore, when each rectangle is connected to a triangle of the cone, the hexayurt will take its shape and stand on its own.
This structure can only be used as a certain reference and can have windows and doors added as necessary. It can be scaled up or down as long as the proportion is maintained.
