Building plan with different eave heights

That picture where it almost looks like 2 floors would be the street side and the view with 1 floor would be from the north, where my mountain side is?

2. If I wanted a symmetrical roof, I would also have to reckon with a lower eaves height at the front and a low knee wall at the front and back

then I would roughly be at the eaves heights you drew, Escroda?

Yes.

Yes. Knee wall height will probably tend towards zero.

I don't understand.
I may have somewhat confusingly marked many eaves heights. In blue, the maximum allowed relative eaves heights, in red the maximum absolute eaves heights resulting from the estimated absolute ground heights, assuming that slanted eaves lines are not desired. Although I once saw a house where that was implemented very elegantly.

I don't like asymmetrical roofs and would build a single-story house without a knee wall with maximum roof pitch. Roof extensions seem to be allowed and the footprint is not restricted - I mean, the limit is so high that it practically does not matter for a single-family house.

Where or how would it say if roof structures had been prohibited?

But there is this stupid 2/3 rule

completely without knee wall
