Street about 50cm above the property - backfill or basement

That would be the southwestern area. In the north or west, does the road then have no slope?

I will ask. Would it be possible to set the house a bit lower? Like finished floor level 10 cm above street level?

You are allowed to do that. But that's exactly when I have my "what does it look like in the rain" problem.

Post your draft. Then we will better see the problem. Is a garage driveway supposed to go there? Slope towards the street?

The street and the sidewalk must absolutely not drain into your property. That is also planned that way. Your house will surely be built up to the building boundary. ergo max. a strip of 3 m? You can easily manage that, even if the house is lower than the street.

Pretty naive. One and a half meters of knee wall, she will hardly be able to "look over the steering wheel," i.e. will only see the bottom edges of the window frames. You only wish for that if you can't count to pi
In the plan excerpt I see a knot line. Does the eaves height refer to the valley or the mountain side?

That is not naive. Rather easy to understand. With a roof pitch of 40 degrees, you can very well install windows in the gables and/or consider double casement windows, dormers, or bay windows. However, I haven't read the development plan. That is your area of expertise.

In the development plan, I had 1 m knee wall and then managed 1.60 m in a bay window. The difference is considerable with a 45-degree roof pitch.

In the site plan excerpt I see a kneading line. Does it mean the eaves height on the valley or mountain side?
