Abstract: An extendable structure adapted to operate between a retracted configuration and at least one at least partially extended configuration includes a box-like body, a foldable floor element, and a foldable ceiling element. The box-like body includes a first and a second upright. The foldable floor element is hinged at a lower portion of the uprights and is configured for being folded and spread out. The foldable ceiling element is hinged at an upper portion of the uprights and is configured for being folded and spread out. In the retracted configuration of the extendable structure, the foldable floor element and the foldable ceiling element are completely housed within the box-like body, which defines an overall size of the extendable structure.
