How are we supposed to know that? You need to provide a few more details. Number of children's rooms, etc.
I understand that no one can know for sure. But maybe there are only one or two reasonable options to place rooms on the upper floor. I suspect the upper floor has only 2 rooms since there are no windows in the middle of the semi-detached houses.
OG: 2 children’s rooms and one bathroom, attic floor parents' bedroom and bathroom, and then there will also be a basement.
And how are the rooms connected? The hallway would have to run along the wall next to the stairs. How is the problem solved that there are no windows between the halves? There is only light from the north and south.
