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.

We are just starting the construction of our single-family home. In hindsight, we would now like to enlarge our dormers to the maximum size. The phrase “in hindsight” implies that construction is already underway – but throughout the thread, it sounds more like the final approval planning is not yet complete. This gives hope that if we knew your ground floor layout or other basics, we might be able to help save more than just poor Kid 3 from darkness through their small gable window.

The introduction "after the fact" implies that construction is already underway – but the tone of the thread suggests it’s more of an ongoing, unfinished final stage of the planning approval process. This raises hope that if we knew your ground floor layout or other basics, we might be able to save more than just poor Child 3 from the darkness through their small gable window. The building permit / planning permission is already approved, and excavation work has started this week. Our construction company is very open to changes. I can still adjust all the window sizes before the appointment with the window supplier.
Hello,
there is an update. I just spoke with the city authorities, and as expected, the 1.50 m (5 feet) distance to the exterior wall is mandatory. I see two options now.
1) Both dormers on the north side will be enlarged as much as possible, but only to the extent that the stairwell and dressing room are not affected.
2) The bathroom dormer is enlarged as much as possible (without it extending into the stairwell), and the positions of the bedroom and dressing room are swapped (dressing room at the exterior wall). This way, the bedroom dormer could be expanded to the maximum size.
The question is, how would it look if the bathroom dormer were about 2.30 m (7.5 feet) wide and the bedroom dormer about 3.20 m (10.5 feet) wide, and therefore not symmetrical to the bathroom dormer? Google doesn’t show any images for this. Does anyone have experience with this?
Best regards,

I'm usually not that much of a perfectionist, but symmetry in dormers is a concern that I find hard to take seriously.
