Hello friends
I have a small problem. We are building an extension to an existing semi-detached house (each semi-detached house is 7 meters wide). During the entire planning period, a dormer window of 3 meters was planned. A dormer with this dimension can also be found at the surrounding neighbors (same development plan). Not with the direct neighbor.
Yesterday I had a phone call with the architect who pointed out the development plan to me:
"The total width of dormers on each side of the building must not exceed 1/2, the width of each individual dormer must not exceed 1/3 of the building width. The maximum dormer width is set at 3.0 m.
Side gables are permitted with a width of max. 1/2 of the building width. The width of dormers and side gables together must not exceed 1/2 of the building width. The wall height of the side gables and the residential building must be identical. The ridge of the side gables must be at least 1.0 m below the ridge of the main building."
According to this, we would be at a dormer width of 2.30. I wonder how the neighbors did it. All neighbors received building permission through the simplified procedure.
Is it possible that if the dormer extends over two rooms, it is considered as two individual dormers?
Does anyone here possibly have an explanation?
Best regards
