An expandable structure has a core structure which may be expanded on a selected side into a composite structure incorporating the core structure and a contiguous expanded section. The selected sidewall of the core structure rotates up to become the roof of the expanded section. The sidewall, endwalls and floor section of the expanded section are hinged to the frame of the core structure and stacked vertically against the selected sidewall/roof but do not take up significant floor space within the core section. Expansion is accomplished by power beams housed within the roof and subflooring of the core structure. The sequence of expansion includes the steps of (a) rotating the selected sidewall/roof to a horizontal position as the roof of the expanded section by power beams housed within the roof of the core section; (b) driving the sidewall of the expanded section outwardly by power beams housed within the subflooring of the core structure; (c) driving the endwalls outwardly; and (d) rotating the floor of the expanded section downwardly to form an extension of the floor of the core section.

An expandable structure, comprising: a core structure having a roof section, sidewall sections, endwall sections and a floor section; a plurality of structural members hinged to a frame of said core structure and vertically stacked adjacent a selected one of said sidewall sections, a substantial portion of said selected sidewall section being hinged to said frame of said core structure, said selected sidewall section being rotatable outwardly to form the roof of a contiguous expanded structure, said structural members being capable of deployment subsequent to said deployment of said selected sidewall, to form a window wall, end walls and the floor of said contiguous expanded structure; power beam means housed within said roof section of said core structure to drive said selected sidewall/roof outwardly to form said roof of said contiguous expanded structure; and power beam means housed within said floor section of said core structure to deploy said window wall, end walls and said floor of said contiguous expanded section.
