Cladding element for a wall and kit comprising at least one such element

A cladding element (1, 1A, 1B, 1C) for a wall, comprising a bottom (2) in the form of a planar and solid parallelogram provided with four foldable edges (4, 5, 6, 7), said bottom (2) forming a parallelepiped when the edges (4, 5, 6, 7) thereof are folded at right angles with respect to the main plane (P2) of the bottom (2), a cover (8, 8A, 8B) in the form of a planar parallelogram provided with four foldable edges (11, 12, 13, 14), said cover (8, 8A, 8B) forming a parallelepiped when the edges (11, 12, 13, 14) thereof are folded at right angles with respect to the main plane (P8) of the cover (8), this latter releasably blocking the opening of the parallelepiped formed by the bottom (2), the assembly, formed by the bottom (2) and the cover (8, 8A, 8B), being releasably inserted into the opening (16) of a parallelogram-shaped frame (15), characterized in that two parallel edges (19, 20) of the frame (15) are triangular in shape and in that the cover (8) is, either at least in part, perforated (10), or the cover (8A, 8B) is equipped with a photovoltaic panel, a sound system or a light signal.
