A vertically and horizontally expandable rigid structure for a plurality of full or partial stories that is comprised of a rigid base, a slide-up roof, one or more floating slide-up/slide-out floors, one or more retractable slide-outs with height-retractable walls. The retracted structure can be transported by a vehicle within the usual legal size and weight limits. The expandable structure can be built as a mobile home, integrated into or attached to a truck, a recreational vehicle, a trailer, or any type of vehicle, constructed as boxed or containerized units or used in any other stationary or mobile way. The sliding mechanisms for vertical and/or horizontal movements are controlled by one or more pneumatic, hydraulic, mechanical, electro-mechanical, or linear methods, or a combination thereof. Each movable section is supported by one or more trusses from the rigid base and/or from the slide-up roof and/or from the structures that are attached to the rigid base at either side(s) of the slides, or by any combination thereof.
