Patent ID: 8104233

Claim:
A method of forming a building structure, comprising: providing a first layer of flexible fabric comprising tensile load bearing fibers having a predetermined load bearing capacity; deploying in situ said first layer of flexible fabric into a first preselected desired shape; and applying in situ a fixing material to said first layer of fabric that fixes the shape of the fabric, wherein applying the in situ fixing material to the first preselected desired shape results in a first self-supporting shell that is structurally adapted to bear both applied tensile and applied compressive loading sufficient to serve as an in situ mold for subsequent layers, wherein the fixed fabric bears both the tensile and compressive loading; applying in situ an intermediate layer of fixed fabric having an intermediate predetermined load capacity and an intermediate shape to said first shell structure; deploying in situ a second layer of fabric having a second predetermined load capacity over said intermediate layer; and treating said deployed second fabric layer in situ with a fixing material establishing a second layer of shell structure that is molded to a second preselected desired shape over the first self-supporting shell, thereby creating in situ a building structure, wherein the second preselected desired shape is different from the first preselected desired shape.
