This Truss Frame can be made with minimal materials.
For instance, 1 Pyramid, with dividing strut ("X1", shown green) and Vertical Base Option, with 8 ft edge lengths, can use 4 x 8 sheets for covering. Only 5 sheets are required and will also cover a 2 ft tall Vertical Base. Here are the 4 x 8 panels:

There is no left over unused panel material for this size and design. Even the left over rectangles made from cutting the right triangles are used. Use plywood or OSB and roof finishing materials for a garden shed, storage, playroom for the kids, etc. Use polycarbonate or corrugated HDPE (Coroplast brand type) greenhouse glazing for a well insulated growing environment. Use our Super Poly for a low cost high performance covering. Attach an inner and outer layer of Super Poly to make an insulating space between the layers.

 Here the larger 10 ft edge pyramid cover pattern is shown. Only 30 ft of Super Poly is required to cover the Octa Pyramid with a 30 inch Vertical Base; using the 12 ft wide Super Poly (12 x 30 ft = 360 sq. ft.)

Make a door:  hinge a section of the Vertical Base, and hinge the triangle panel at the X1 strut, or removeable triangle or flap section if using the Super Poly.
