This is a 2/5 38' diameter dome, (1000 s.f.) built with prefinished panels, including insulation, consisting of Cellutex & Reflectix, plus a roofing material called Peel & Seal. Kits & books are available, which include cut and drilled lumber for framing, along with patterns for insulation and roof sheathing.

One hot water panel is for hot water heating and another is for slab heating with tubes in slab.
One fixed panel is for hot air heating.
Drain back hot water & solar panel mounted on rotating wood tracking frame (material cost $330)
Hot water energy stored in insulated concrete floor.
Tracking support with solar cells and hot water collector.
The following is a 11' diameter emergency shelter built from OSB used as an exterior sheathing, using ripped 2x4s as edge connectors. Total cost was less than $100. Built by Chris Hampton, with design and cut out patterns done by Mountain Truss. The structure will require a treated base board plus a final entry panel installed with oblong opening cutout. For short term, emergency conditions, blue plastic can be used as an exterior weather proofing, but the structure has the strength to allow application of standard roofing, and the insulation can be done on the inside with an application of Reflectix done at a later date. The structure can be disassembled and stacked with a height of less than 18 inches, and a foot print of 4' x 4'. This structure was assembled by a single individual using a screw gun in approximately 2 hours. The connectors are cut 4 inches shorter than the edges they connects, and there are three different angle settings used in the connector fabrication. The angles are shown on the overall 3D drawing. You can use a reflective elastomeric paint for the roofing, but you have to use a quick setting primer, as the OSB has a tendency to swell when in contact with water. The edges then can be sealed with silicone caulk.
