Floor plan design for a hillside house with 5 children's rooms

In the north, move the walls to the left. Did you notice that because of the wide staircase in the north, you only have rooms measuring 2.50? I think that is disproportionate. As a result, you have a greater width in the middle for accessing the rooms than the rooms themselves in the north. 2.50 to 4.00 meters...

Basement with bathroom from the upper floor and staircase shifted to the west. Problem: it becomes too tight in the hallway at the back. Maybe the children's rooms need to be shifted a bit?

And upper floor with the same changes

... you wrote hip roof as your desired roof in the initial post. In the photos of the surroundings, I only see gable roofs. Would a hip roof be allowed?

If not, then a gable roof will also do. We are practically minded. The neighbor 4 houses down also has a hip roof. I don’t recall that the roof shape was specified. I’ll ask the architect next week.

Walm is sleeker! More zzzzisch.....

Hip roof is sleeker! More ssssssh.....

I think so too . But it would also work without it.

I would like your opinion, as down-to-earth and professionally experienced from my point of view : is building with 30 cm Ytong "okay," or does it have to be kfw55 with 36 cm stone and 18,000 surcharge?
