Abstract: A self-erecting structure system including an external structure apparatus including a plurality of external structure modules, each module comprising a plurality of legs, an internal structure apparatus configured to be temporarily be positioned within an area bounded by the external structure apparatus, the internal structure apparatus comprising a plurality of internal structure modules, and a platform member comprising, an inner aperture through which the internal structure apparatus may pass, an internal structure locking device, a plurality of outer apertures through which legs of the external structure apparatus may pass, a plurality of external structure locking devices, a primary lifting system, and a secondary lifting system configured. One of the primary lifting system and the second lifting system may raise the internal structure apparatus until a lower end thereof can be fixedly attached to the platform member.
