Why standard wall units fail here
A catalogue wall unit has a fixed height. Under a 35-degree slope that leaves either a wide gap or a cabinet cutting through the ceiling. Both waste storage and look improvised. We draw the slope as a line in the design and step the cabinets along it.
Three proven solutions
First: stepped wall units with a level top edge so the joints stay horizontal. Second: open shelving in the low zone where nobody could open a door anyway. Third: a full-depth worktop that makes the slope usable as surface. The knee line decides which mix fits.
What the survey needs
We need the clear height at three points along the slope, the knee line, the wall distance of the eaves and the position of roof windows or vents. Those four readings are enough for a first design. A binding survey follows before production, because old roofs are rarely straight.
Work height and ergonomics
Under a slope you often find the sink or hob because services sit there. Then work height must suit the person, not the slope. We check whether an 86 cm or 90 cm run works in front of the slope and move functions if your head would hit.
Light, colour and material
Slopes swallow light. Light matte fronts and a worktop in a similar tone keep the room open, and indirect lighting under the slope brightens the low zone. For fronts we recommend coated surfaces because they clean more easily in niches than veneer.
