ABSTRACT:
The present invention provides a method and apparatus for the construction of a low-cost building structure through the synergistic composition of material, process, and structural design. In a first embodiment, a specially fashioned balloon, in the shape of a house, is used as a one-sided form, and is sprayed with a building material formulation. The building formulation may include: structural material, reinforcing material such as fibers to eliminate or minimize separate structural reinforcement, a gaseous bubble material (to provide thermal insulation), and other ingredients such as fillers, strengtheners, bulk-formers, accelerators, coloring agents and dryers. The structure can be created rapidly, and the balloon deflated and removed in minimum time, all by a few as 2 men. The low cost of the labor and materials and equipment used according to the present invention result in a more economical method of creating a building than any presently known method.
