Floor plan optimization of a single-family house with a basement on a small plot

Regarding the parking spaces and garages, it is as I suspected. These are not allowed outside the buildable areas.

That's how I also read it. I can't imagine that an exception would be granted for a parking space there. Apart from that, would something like this be conceivable in terms of eaves orientation (regardless of size, etc.)?

not even a parking space.

Ok we understood that differently. BU also said parking space uncovered yes, all covered no... We previously thought it might be like this: But if you all say that doesn't sound right, we need to investigate further. Explicitly excluded are only covered parking spaces outside the building window, covered spaces on the street side are allowed, so we were told that covered parking spaces are allowed in the 3m zone...

No, as I read it, no parking space is allowed within the 3m distance on the right side.

Although unusual, according to the wording, parking spaces are allowed on the street side. Since next to the house is not street side, they would not be permitted there. Since I can't see any sense in this stipulation, one should inquire more precisely with the city planners.

would something like this be conceivable regarding eave orientation

Unless there are further design regulations, yes.

covered spaces are allowed on the street side

I don't see it that way. IMHO only uncovered parking spaces are allowed.

that covered parking spaces are allowed in the 3m zone

Same here. Do you maybe mean "uncovered parking spaces"?

Hi ! Can you still answer the 2nd question: How wide would a street-facing gable probably be if there were only 2 stories? What is usual?

Ok we understood that differently. BU also said uncovered parking space yes, all covered no...

When I look closely at BU's sketches, he did not place the car on the 3m verge, but within the construction field (thus correctly according to regulations). The terrace on the other side is therefore only about 2-3m or so and almost directly at the neighbor's fence. I think he already recognized that correctly, but just didn't say anything about it.

Hard to say. Since [Traufständigkeit] is fixed, the dormer must not appear prominently. But that is then in the eye of the beholder. With one third of the wall of the main building body, you are usually on the safe side. Your proposal could therefore meet resistance. The justification for the development plan could be helpful. The stipulation "traufständig" should be explained there. Maybe the basic features of the planning can be derived from it.
