Gable / Gable - Definition

I have a question about the definition of a dormer or a gable:

And what is prescribed in the development plan is that for roof structures a minimum distance of 1 m must be maintained from the lower roof edge and from the ridge. In addition, the eaves height may be max. 3.50 m.

Is the attached construction type a gable or a roof structure, or would the building authority approve such a type of construction?

Does the upper eave on the dormer/gable also count towards the 3.50 m rule? Or is the minimum distance to be measured from the ridge height of the dormer or gable or from their eave? And how is the distance measured (as a height difference in the section or on the roof surface)?

I interpret this to mean that the 1m minimum distance of the dormer from the gable of the house is measured such that the gable of the dormer must lie at least 1m below the main gable. Therefore, the house shown would not comply with the building regulations. Whether it can still be approved, you can inquire at the building authority before submitting the building application. Someone there is usually willing to help. In our case, a maximum house width is specified in the building regulations, which we exceed by 1.5m. This was permitted by special approval, as was shifting the building window one meter backward and constructing a carport outside the building window. Sometimes it helps to ask politely and present the concept.

A gable

Would the building authority approve such a design?

Ask them. Your development plan does not permit it as is.

Does the upper eaves of the dormer/gable also count towards the 3.50 m rule?

Yes.

Or is the minimum distance to be measured from the ridge height of the dormer or gable or from their eaves?

The minimum distance does not apply since this is not a roof structure.

And how is the distance measured (as height offset in section or on the roof surface)?

Your roof structure is inadmissible if any part of the roof structure is less than the minimum distance away from any point of the verge, ridge, or lower roof edge. Since further explanations are missing, unlike with the height of roof structures, the true distance in three-dimensional space is meant.

So not the height offset but measured along the slope, right?

Did your architect actually plan it that way? He was aware of the development plan, wasn't he?

Yes, that comes from the architect … but he also said that "not all details have been taken into account yet and that this will happen in the course of the building permit planning."
