Besides emergency shelter, this structure could also be a playhouse, dog house, temporary work building, astronomy observatory, deer blind, EMI shield enclosure, ice fishing house, orbital habitat, green house, bullet proof enclosure, animal shelter, fire shelter, Burning Man habitat, and so on. All portable, cheap, and quickly erect-able. Just change the size and shape to meet your needs and select the appropriate materials. Variations of this concept can also make solar concentrators, dish antennas, and domes (maybe the world's first one peice, fold up dome!)
The example shown here is a very basic seven sided yurt type structure, made with Home Depot Wardrobe boxes, Gorilla tape, and spring clips. The wardrobe boxes are convenient because most of the creases needed for folding are already there.
Patent Pending. More variations to come, showing additional features and options. Thanks for your interest.
Step 1: Materials and Tools Needed
Gorilla Tape (15 feet) - Any kind of reinforces tape will probably work, such as duct tape.
Spline Roller tool (1) - Normally used for pressing in the spline on window screens, it is also good for creasing the card board at places that need to fold.
Spring Clips (7) - a convenient device for holding the structure together.
Other tools you may find useful - tape measure or yard stick, markers, scissors, knife, Elmer's Exterior Wood Glue
