Hello friends
I have a small problem. We are extending an existing semi-detached house (each semi-detached unit is 7 meters (23 feet) wide). During the entire planning phase, a dormer measuring 3 meters (10 feet) wide was planned. Dormers of this size can also be found on neighboring houses in the area (same planning regulations). But not on the immediate neighbor’s house.
Yesterday, I had a phone call with the architect, who pointed out the planning regulations:
“The total width of dormers on each side of the building must not exceed half of the building’s width, and the width of each individual dormer must not be more than one third of the building’s width. The maximum dormer width is set at 3.0 meters (10 feet).
Side gables are allowed with a maximum width of half the building’s width. The combined width of dormers and side gables must not exceed half of the building’s width. The wall height of the side gables and the main building must be identical. The ridge of the side gables must be at least 1.0 meter (3 feet) below the ridge of the main building.”
According to this, the dormer would have to be 2.30 meters (7.5 feet) wide. I wonder how the neighbors managed to do it. All neighbors received their building permits via the simplified procedure.
Could it be that if the dormer extends over two rooms, it is counted as two separate dormers?
Does anyone here perhaps have an explanation?
Best regards

The answer was 3 meters (9.8 feet). If the house is 9 meters (29.5 feet) wide... okay, I assume that is not the case and that all semi-detached houses are uniformly limited to 7 meters (23 feet). Since you already know your neighbors, you could actually ask how their planners solved this issue.
A 12-year-old development plan is not exactly from a different architectural era to the point where official design requirements would regularly be waived. In any case, the detached position is unlikely to be possible with the current plan, since the side gable in your photo violates this specification:

The wall height of the side gables and the main residential building must be the same. The ridge of the side gables must be at least 1.0 m (3.3 ft) below the ridge of the main building. Does this mean that the main roof and the cross-gable must have the same eaves height, that is, the same knee wall height (possibly zero) as well?

In the shell construction, we have a knee wall of 1.10 meters (3 ft 7 in).
I took a look around your new development area. It seems like no one is really adhering to the design guidelines. So much text, yet so little effect.
1. Dormer < 1/3 wall length
2. Secondary gable with the same wall height
3. Secondary gable with a higher eaves height
4. Cross gable with a shed/flat roof
5. Dormer > 1/3 wall length
I would have expected only 1 and 2 to be allowed. But 3, 4, and 5 are not isolated cases. Your planner should check with the building authority; the written regulations already include later policy decisions regarding the design.

and a few others have come together as well.
I already spoke with the planner today.
He will check on that.
Looking forward to seeing how it turns out.
For your information
There is no general binding decision.
The lady from the municipality told me that my construction project can have a dormer up to 2.40 meters (7 feet 10 inches) high.
It is also not considered a gable.
I then asked her how others have handled it.
I showed her some pictures as well.
She will look into it and get back to me.
I think I will have to accept it as it is.
Many thanks to @Escroda.
