ᐅ Setback area, flat roof, building permit (also known as planning permission)

Hello everyone,

I have a question regarding setback distances and hope someone can help me.

Our three-story house with a flat roof, as shown in Image 1, was not approved because the setback distance could not be maintained as planned.

Therefore, the wall on the third floor was set back to meet the required setback distance. See Image 2.

Now, the roofer wants to build the roof so that it extends beyond the wall instead of aligning flush with it. See Image 3.

In my opinion, this would violate the setback distance again, as indicated by the red line in Image 3. Or is the setback distance still maintained since it is measured from the wall, as shown by the green line?

I hope I have explained myself clearly and that someone can answer my question.

In Lower Saxony, for example, a roof overhang up to 50cm (20 inches) is disregarded. It is supposed to be that way. Just as a reference. But don’t ask me where I know this from or where it is stated.
