Lamellar construction double-U with adjustable size has several U-shape components mounted on two strip (1) in transverse direction by bolting, dowelled joint, mortising, so that by stepping the lamella a storage, seating or useful space is formed. In the component a further U-shape component of same construction (3) is so inserted, that by stretching out and telescoping, a maximal adjustability of dimensions of the entire structure.
