I uploaded the current visualizations of the planner with my post
Sorry, I hadn’t seen that.
The rooms planned here offer so many possibilities (bed in the niche,
Yes, that’s all correct, but if floor-to-ceiling windows are badly planned, and thus the otherwise obvious “private” bed niche cannot be realized, then the windows should be reconsidered in order to give the large room many different furnishing options.
Regarding the facades

Northwest side The two tall hallway windows are impractical for two reasons. They will probably be fixed glazing, so cleaning from the outside will be difficult. And between the bathroom and the parents’ area, if there were a wider window with a normal sill height, a chest of drawers could fit, for example for bedding or bathroom supplies or extra blankets etc.
East side So far, quite okay .. I don’t know if these connecting elements between the windows are necessary. Is that just a paint design or some special material?
Southeast side As mentioned, I would not install floor-to-ceiling windows in the children’s rooms. Wider “normal windows” generally provide more light and also allow the room to be furnished more variably.
West side As I already wrote in the room assessment, I would widen the terrace door there to 2 m and try to adapt the kitchen window. In doing so, really consider the kitchen’s content.
