ABSTRACT:
The invention describes a method of constructing a building involving the assembly of a rigid skeletal framework of struts defining the contours of the desired building which is for example domed, or part-barrel shaped. A membrane or envelope of plastics material is inflated within the framework to lift the struts from a state of compression under their own weight into a state of tension. The membrane is then coated on at least one side with settable material such as concrete or other glass fibre reinforced material and the membrane deflated when the material has set. In an example of the invention, support zones at the junctions of the struts support the set material.
