The typically classic arrangement of floor unit, niche and wall units is not used with CONCEPT 40. The principle design is a two-dimensional cladding of the entire wall above the worktop with a grid of 40 cm high cupboards.
The lift-up doors are opened separately. The cupboards are sitting directly on the worktop with CONCEPT 40. This opens up the entire working depth.
Important function building blocks such as extractor and taps are unobtrusively integrated in this grid.

With Concept 40 the term "wall units" has been newly defined. The design principle is the flat covering of the total wall space above the worktop. The horizontal line is achieved with 40 cm high front runs. As a particular design characteristic, these fronts have griprails in stainless steel look on the bottom edge (handle number 806.405). Further handle styles are not available. Always three or four fronts are fitted as flaps above each other on 120 cm or 160 cm high midway units. The upper most are side hinged - the others are flaps which, on opening, move parallel in front of the above doors.
