Hello,
we are currently at the beginning of building our single-family house. In hindsight, we would like to enlarge our dormers to the maximum allowed size (50% of the building length) because we are struggling quite a bit with a knee wall height of 60cm (24 inches). For us, that would be 5.5m (18 feet) per side with 2 dormers, so 2.75m (9 feet) each. This change would affect the bedroom and the bathroom (the main reason for the change is the bathtub).
Now, the building permit / planning permission states the following about the dormers:
Length/Width of roof extensions, roof cut-ins, and cross gables on each roof side together max. 1/2 of the respective building length (total width/length). Distance to the ridge at least 1.0m (3 feet 3 inches) measured on the roof surface.
Lateral distance to the gable of the main house, to house offsets, as well as to cross gables, roof extensions, and roof cut-ins at least 1.5m (5 feet) (measured at the outer intersection of the exterior wall and roof covering).
The length and width are clear to me and fit within the limits. But I am a little uncertain about the lateral distance.
Does the "exterior wall of the dormer" have to be 1.5m away from the "exterior wall of the main house," or from the edge of the roof?
Sorry for the silly question, but if the distance only applies to the exterior wall of the main house, I would probably have to apply for a variance for 40cm (16 inches).
Thank you all.

(measured each time at the outer intersection of the exterior wall and roof covering). This seems clearly to imply a hypothetical "zero" roof overhang at the verge.

Do I have to measure the distance from my "dormer exterior wall" to the "main house exterior wall" as 1.5 m (5 feet) or to the edge of the roof?To the gable wall, meaning the exterior wall, with a distance of 1.5 m (5 feet). That’s how I understand it.

Regarding the gable, that is the exterior wall, a distance of 1.5 meters (5 feet). That's how I read it.Thank you for your responses. It looks like I’ll have to check with the building authority on Monday to see if something can be done. I don’t expect they will be flexible.

I don’t think they will respond to that. Simply put, probably not. You need solid reasons why this is absolutely necessary.
Show us your plans and convince us. If you succeed, dealing with the authorities will be a breeze.
I only have the picture here on my Chromebook, but it’s still visible.
Basically, it’s just about the dormer in the bathroom. We would also do one in the bedroom to keep the overall look symmetrical.
Currently, the dormer would be 2.0m wide (6.5 feet), with a maximum allowed width of 2.75m (9 feet), and we would like to use that full width. Our knee wall height is 59cm (23 inches). The problem is that our bathroom is along an exterior wall, so I’m only allowed to enlarge it by 25cm (10 inches), otherwise I would fall below the required 1.50m (5 feet) minimum distance.
