Detached single-family house on a slope with a granny flat

I somehow can't understand why the parents' bathroom is the one that gets the bathtub. When the kids want to take a bath (teens like to bathe a lot and sometimes late into the evening), they have to run through your dressing/sleeping area every time... Even if the teenage daughter wants to take a bath with her boyfriend (as a father you don't want to think about it but it supposedly happens :P), they have to run through your area.

And otherwise they never get to enjoy the "luxury" of using the nice spacious bathroom.

I find the division into kids' and parents' bathrooms strange anyway. I would understand a parents' toilet at the bedroom (if you want, with a shower) and one big family bathroom with a bathtub. That way everyone would get to enjoy the big bathroom.

The northwest view has the filename northeast. There you can also see the entrance.

I saw the entrance. But I just can’t get along with the rotated ridge direction in the site plan and the new west, which is east.

the North-West view has the file name North-East

Yes, and the North-East view does not exist, even though the 6m high boundary construction would be visible there. I don't believe that is allowed – at least not according to the state building code; the development plan would have to include exceptional regulations for that – and the neighbor would certainly not be happy if his South-West side were so blocked off. However, I would also be surprised if the architect, who pushed the floor area ratio, eaves and ridge heights to the limit, had not taken that into account. A site plan with the actually planned house, heights, sealed surfaces, and development plan would be interesting and helpful.

In the northwest view, the entrance of the granny flat can be seen. His car is also parked there.

??? How does the car get there?

I have the feeling that a few rooms are too small, e.g. the bathrooms. It will be far too cramped in the children's bathroom. Why the [Einliegerwohnung]? Please not to save money...

Then I'm not the only one with a board in front of my head
