Deviation of dormer height from building permit

No no, somewhere I actually read that it might be possible to subdivide again. With a fixed central post.

That must be a misunderstanding, since it concerns the clear access opening for the rescuer. The rescuer is supposed to enter here or be able to reach out the rescued person. The clear dimension is not a formality, but must function practically in an emergency.

That must be a misunderstanding, since it is about the clear climbing opening for the rescuer. The rescuer is supposed to climb in here or be able to pass the rescued person out. The clear dimension is not a formality, but must practically work in an emergency.

Not quite right. On the one hand, it is about climbing through and in addition about laddering. Thus, even with a normal window, the rescuer only has about half the window width to climb through. I read an article about this some time ago in Feuertrutz (fire protection specialist magazine).
