Floor plan with basement on sloped land

And somehow the distribution of the square meters is wrong... The bathroom and bedroom have more space than the children's rooms... It actually needs to be mirrored, I think, or the stairs moved up a bit so that the rooms in the southwest become bigger for the children...

And we have the entrance to the bedroom through the dressing room and I love it!!!

So that means the floor plan as it is now on the upper floor is not so bad? The rooms not too narrow? I would now plan both children's rooms at the front with a dormer for a window facing SW
