Development plan full floors / floor knee wall?

Hello everyone,

on Friday we very unexpectedly received approval for a building plot. We are still very new to this and have little knowledge. The development plan is still very straightforward (from 1990). Can someone tell me exactly what this means?

Number of full floors
Maximum allowed: 2 full floors, whereby the upper floor must be located within the roof space at a roof pitch of 42° - 50°.
Knee walls must not exceed the dimension of 0.5 m measured from the top edge of the ceiling to the intersection of the outer edge of the masonry with the top edge of the rafters.

What exactly does this mean? Complete 2 full floors or how high may the knee wall be?

Thank you dear ones

Tell me (without link!) what the name of the development plan is, then we can read the justification. I would understand what we can read from your words as meaning that you are also allowed to build a straight-walled upper floor if the roof above it is pitched at less than 42°.

You are not allowed to split the 2 full floors like a town villa, so you must accommodate the upper floor under a regulated roof (under a regulated roof). With a 42 to 50 degree roof, that should be easy. This then results in an attic.
I assume that the maximum height is not regulated.
The knee wall: it is regulated so that it is not visually conspicuous with its 50 cm on the outside.
That should be enough for the answer for now...

No. The way you ask, you are misunderstanding the term full floor. A full floor is more than a town villa.
As already mentioned: the calcium silicate brick is not significant regarding the 50 cm. More precisely, an architect can calculate it with rafters and transitions.

Thank you for your message - we don’t want a full second floor anyway. Our question is rather whether a maximum of 50 cm knee wall is allowed or if it may also be higher? :) We will enter into talks with the architects in the next few weeks :)

If you put interior walls in the upper floor, this can raise the knee wall. Of course, at the expense of living space. But you will not be allowed to exceed the outer dimensions of the knee wall. Have a look at 'mansard roof'
