Claim 7:
8. Method for moving an extendable structure (1) comprising at least the following steps:
arranging an extendable structure (1) adapted to operate between a retracted configuration and at least one at least partially extended configuration and comprising:
a box-shaped body (2) comprising at least one upright (3, 4), in the retracted configuration of the extendable structure (1) the box-shaped body (2) defining an overall size of the extendable structure (1),
a foldable floor element (11) hinged in proximity to or at a lower portion (3b, 4b) of said at least one upright (3, 4), and
a foldable ceiling element (14) hinged in proximity to or at an upper portion (3a, 4a) of said at least one upright (3, 4),
at least one lateral wall (5, 6), in the retracted configuration of the extendable structure said at least one lateral wall being placed in proximity to said at least one upright and laterally delimiting the box-shaped body, defining one side thereof;

in the retracted configuration of the extendable structure (1) the foldable floor element (11) and the foldable ceiling element (14) being housed within the box-shaped body (2),
spreading out the foldable floor element (11) so as to determine a transition of the extendable structure (1) from the retracted configuration to said at least one at least partially extended configuration or folding the foldable floor element (11) so as to determine a transition of the extendable structure (1) from said at least one at least partially extended configuration to the retracted configuration, said step of spreading out or folding the floor element (11) being attained by means of a first actuator,
spreading out the foldable ceiling element (14) so as to determine a transition of the extendable structure (1) from the retracted configuration to said at least one at least partially extended configuration or folding the foldable ceiling element (14) so as to determine a transition of the extendable structure (1) from said at least one at least partially extended configuration to the retracted configuration, said step of spreading out or folding the ceiling element (14) being attained by means of a second actuator;
rigidly translating said at least one lateral wall;

wherein the step of spreading out or folding the foldable ceiling element and the step of spreading out or folding the foldable floor element are simultaneous;
wherein the step of spreading out or folding the floor element and the step of spreading out or folding the ceiling element cause the rigid translation of said at least one lateral wall; and
wherein the extendable structure (1) is the extendable structure of claim 1.
