Purlin distance from exterior wall or roof

Let's be honest. If you want to squeeze a 2.75 dormer into the bathroom, it looks really awful from the outside. The dormer visually slides off the roof. Can't you just raise the KS, or have you already exhausted all the height options?

I see a big problem with even getting onto the bed or getting out of bed on the roof side. The normal movement of first sitting down on the side of the bed is not possible at all. The walk-in closet is also only accessible halfway. On second look, the windows on the gable sides with RBM 76 are very, very narrow. Why go over dormers there? Simply put: put the bed under the slope and enlarge the windows. That doesn’t change the dormer problem, but it positively improves the usability of the bedroom.

Honestly. If you want to squeeze a 2.75 dormer into the bathroom, it looks really bad from the outside. Visually, the dormer slides off the roof.

That works, it’s not enclosed by the roof. They are floor-to-ceiling windows.

No, we’re already at the maximum.

I see a big problem getting into the double bed on the roof side or getting out of the bed there. The normal movement of first sitting down on the side of the bed isn’t possible at all.
The walk-in closet is also only half accessible.

At least the issue with the double bed would be good for a solution.

RBM

They are floor-to-ceiling.

At least the thing with the double bed would be good for an exemption.

I don't see it that way, since you are making it complicated for yourselves and want to use the attic turned 90 degrees from what the gable and roof specify. See my suggestion #7

Simply not like that. You have to have good reasons why it absolutely has to be this way.

But my/our opinion should not stop you from going to the building authority, although in my opinion you can talk more into confusion there than your architect can argue. I see the argument rather in the socio-family reasons, to do justice to 3 (three!) children and to offer everyone a functioning home.
What does say?

Are floor-to-ceiling

Floor-to-ceiling slots... in our 80s also only modest light gets in. At least no light comes in from the left and right of the window.

these we would also like to use.

That is not very convincing. The municipality has enacted a design statute. That is a "municipal law." You do not want to comply with it and must provide good reasons for doing so. If you want to run a red light, you must also have good reasons, e.g., a woman passenger shortly before giving birth. Melting ice cream from the Italian will probably not be accepted by the police. In any case, I cannot find any reason for an exemption from your floor plan.

So, I had the gentleman from the city on the phone, I don’t have to submit an exemption yet. Because I also have to build a conservatory for the enlargement of the dormers to maintain the one-and-a-half-story structure, I should simply send him a small building application including the conservatory and dormers. The building authority will then decide on it.

Looking forward ops:
