ᐅ Knee wall height – term used in the building permit / planning permission?

Hello,
I am currently trying to understand the development plan, and there is a phrase I don’t quite get:
“The height of knee walls, measured from the top edge of the ceiling to the intersection of the exterior wall surface with the top edge of the ridge beam, must not exceed 0.5m (1.6 ft).”
Could someone explain this to me (maybe with a drawing)?
If it’s relevant, here is some additional information:
- Mixed-use area
- Number of full floors: 1 (mandatory)
- Floor area ratio (FAR): 0.25
- Site occupancy index: 0.3
Thanks in advance
Best regards
Specki

Your access to the local authority is good.
Does the same zoning plan apply to the opposite side of the street? If so, has the area been divided into different height zones?
Perhaps the restriction on the knee wall height can be waived, citing the solid construction opposite as justification?
Also, ask how the knee wall height is defined by the local authority. As you can see above, this can make a difference of up to 50cm (20 inches) in structural height. Every centimeter helps!
Are there any buildings on your side of the street that might not comply with the zoning plan? If so, take photos of them to show the local authority.

In practice, from my point of view, you can build up to 32cm (13 inches) above an 18cm (7 inches) high purlin. This would be what I call a "vacuum cleaner knee wall."
You can name the zoning plan here ("Posemuckel No. 234 in the cool valley," links are not welcome here).

"The height of knee walls, measured from the top edge of the ceiling to the intersection of the outer edge of the masonry with the top edge of the purlin, must not exceed 0.5m (20 inches)."
Specki schrieb:That makes no sense, since "max. 1 full story" and "1 full story" are practically the same. Theoretically, without the addition "mandatory," a nitpicker could place an attic story without a ground floor underneath *LOL*
Number of full stories: 1 (mandatory)
Solveigh schrieb:No, purlin is correct. After all, the measurement is not taken up to the top edge of the roof covering; unfortunately, the drawing in post #2 is incorrect.
What does top edge of the purlin mean? Shouldn't it be the top edge of the rafter?

Especially on the opposite side of the street, there are buildings with 3 full stories...
