Stockwerk appears to negate its material properties. Due to the cut side walls the solid wood construction becomes a foldable object reminiscent of a compressible paper model. As an alternative to plug and screw connections this shelf needs no assembly and is delivered folded up. The side walls are split, mitred and fixed with piano hinges. The system is fully linked together; the shelves just have to be unfolded. The system is self-stabilizing via the mitre-chamfer on the side wall edges. Despite having fewer and simpler production steps, a complex functional system is possible. The final height of the shelf is customisable, as some compartments can stay closed according to requirements.
