Take your measurements from floor to ceiling, indicate the height of the baseboard.
For slopes (attics, staircases), please note several measuring points so we can evaluate the slope and carry out the right layout.
For any architectural constraint (door, window, headboard, cupboard...), please indicate their dimensions H x W and their position related to the floor/ceiling and the wall corners.
We add safety margins which are taken into account in the calculation of the square meters needed when drawing up the quote. This is to avoid a discrepancy due to the non-verticality of the walls or a mistake when taking dimensions.
