In kitchen planning and spatial design, horizontal lines play an architectural role of great importance. Custom door formats allow for individually tailored joint divisions, creating a sense of refined visual harmony throughout the space. In the example shown, the division of fronts and wall panels follows the upper edge of the worktop — a detail that speaks to the precision and thoughtfulness inherent in premium German kitchen design. Depending on worktop thickness, plinth height, and cabinet height, the joint position will naturally vary and is carefully adjusted to achieve a seamless, flowing result.
