Hello,
can someone explain how the knee wall height is correctly calculated?
I currently have quotes from two builders, and they calculate it differently.
Data
Knee wall height 80cm (31.5 inches)
Roof pitch 38°
Wall thickness 36cm (14 inches)
1. 80 cm (31.5 inches) knee wall height on the outside corresponds to about 100 cm (39 inches) on the inside
2. 80 cm (31.5 inches) knee wall height on the outside corresponds to about 65 cm (26 inches) on the inside
Excerpt from the development plan
The knee wall height of the attic must not exceed 80 cm (31.5 inches). The knee wall height is defined as the distance between the top edge of the attic floor and the intersection line of the outer surface of the wall with the underside of the roof covering.
I am not asking for an exact value, but which builder is wrong?!
Best regards
Chris

On the other hand—why should you do that, aside from an initial introduction to house building in Nauen? The temporary building partner you choose is responsible for compliance with the development plan. If an architectural firm is involved, it is among the planner’s duties to adhere to the development plan’s requirements.

Knee wall 80cm
Roof pitch 38°
Wall thickness 36cm
1. 80 cm knee wall outside is about 100 cm inside
2. 80 cm knee wall outside is about 65 cm inside
Excerpt from development plan
The knee wall height
of the attic must not exceed 80 cm. The knee wall height is defined as the distance between the top edge of the attic floor and the intersection line of the exterior wall surface with the lower edge of the roof covering.
Chrisbo schrieb:That is within their rights; with the development plan, the city can, among other things, set specific height requirements.
The city of Nauen refers to the development plan..
Chrisbo schrieb:Of course, you can do that. The city of Nauen likely offers building consultation services for homeowners.
Would a meeting at the local building authority be an option?
