ABSTRACT:
Shelters and methods of making them are disclosed which include a basic module that has a frame over which a flexible fabric cover is fitted and appropriately attached so that when distended it will define the configuration of the module. A reinforced rigid plastics foam material is adhered to the outer surface of the flexible fabric cover, and a protective waterproof coating is adhered to the outer surface of the rigid plastics foam material. If desired, portions of the frame can then be removed leaving a self-sustaining shelter.
