A dome building structure employs an inflatable form having a peripheral edge secured to a base. A network of cable-like members overlies the form and is secured to the base so as to restrain pressurized inflation of the form to prevent tearing. A layer of insulating foam is applied to the inner surface of the inflated form followed by attachment of a reinforcing mesh and application of a cementitious layer sufficient to embed the mesh. Internal ribs are formed to directly underlie the network of external cable members which may be interconnected to the internal ribs to assist in support of the ribs until they become self-supporting of the dome. The external network of cable-like members allows the form to extend convexly outwardly or pooch through interstices in the cable network creating smaller radii of curvature to better withstand inward buckling.
