In our drawing, the kitchen window sill height is listed as +1.06 m (3 ft 6 in). To me, this means a sill height of 1.06 m (3 ft 6 in) measured from the finished floor. With a kitchen counter height of 0.91 m (3 ft), this would leave 15 cm (6 inches) for things like power outlets. This is also how the kitchen designer calculated it. Now the bricklayer says that the sill height refers to the structural shell and that an additional 20 cm (8 inches) must be added to the raw floor level for underfloor heating and the screed. Then the window would only be 86 cm (2 ft 10 in) above the finished floor, making it 5 cm (2 inches) lower than the kitchen countertop. That can’t be right. What is correct?

How should the +1.06 be understood here? For the living spaces, it says +1.00. It means 1.00 (+/- tolerance!) or 1.06 (+/- tolerance!) meters above 0.00 – but here lies the main issue: whether 0.00 refers to the finished ceiling height reference point (OKRFB) or the top edge of the finished floor. Usually, it means the top edge of the finished floor, but this assumes that the difference between the rough floor and the finished floor actually matches the plan – and that’s where the problem lies. Neither the bricklayers, nor the screeders, nor the tilers are precision workers. For good reason, people say “rule of thumb” and not “rule of angels’ hair.”
