In kitchen planning and spatial design, horizontal lines play a defining role. Custom door formats allow for individually tailored joint divisions, creating a sense of refined architectural coherence throughout the space. In the example shown, the alignment of fronts and wall panels follows the upper edge of the worktop — a detail that elevates the overall composition with flowing, clean lines. Depending on worktop thickness, plinth height, and cabinet height, the position of the joint varies and is adjusted accordingly to achieve a harmonious and elegant result.
