Eaves height of a three-gabled house (bay window/extension, ...)

Good evening everyone,

we are planning a house with a gable roof and a third gable and have a question regarding the eaves height.

The development plan contains the following specification:
"The maximum permissible eaves height (eaves-side intersection of the outer edge of the enclosing masonry with the top edge of the roof covering) may be a maximum of 6.25m above the top edge of the finished ground floor slab. Subordinate building recesses are not affected by the eaves height specification."

How is the eaves height determined for the third gable? According to our understanding, it would be line (1). Is that correct? Or is the eaves height of the gable measured with line (2) (the development plan refers to the eaves-side intersection)?



Have a nice evening!

Even the cropped image still allows the assumption that a limitation of this "roof structure" to one third of the length of this side has been observed, and one could therefore consider the dormer as subordinate - with the consequence that compliance with the maximum eaves height by the "main roof" is sufficient.

Thanks for the note regarding the subordinate component.
If the bay window is not considered a subordinate component, how would the eaves height then be measured?

Correctly understood. Although the pedantic surveyor finds the upper line end drawn too imprecisely. To avoid misunderstandings:

a limitation of this "roof structure" to one third of the length of this side has been observed, and one can consider the dormer as subordinate in this respect

I have read that several times but have not found any evidence for it so far. In NRW at least, there is no such one-third rule and a dormer is never considered subordinate here.

Then it seems illogical to me that you vote for "1," because then it should rather be

(for the third gable) that counts (?)
