Personally, I find the ground floor generally too angular. I prefer it straightforward, versatile. A matter of taste.
Upstairs, I find the room sizes strange. The bedroom is relatively small, the bathroom huge or almost too big at 19 sqm. In between is the dressing room, which has a door in every direction and probably a window to the north. 7.5 sqm, into which a good 3m of wardrobe, maybe 4m with corner solutions, will fit. But then you only have clothing stored there; you also need some space to dress, maybe a chair, something to put things on. At the latest, when the partner wants to go to the bathroom, you’ll be standing on each other’s feet.
In other words: I find 10+7.5 sqm = 17.5 sqm for a bedroom with a large double bed and wardrobes just barely "okay." To reduce it further with an additional wall, door, and window, minus the additionally required "circulation area"—everyone has to decide for themselves.
The kids’ room is an absolute palace. I don’t want to start a faith war, so just the question: Is that intentional, or does it just result from the room layout?
If the latter question applies to one or the other room, maybe the "reset" button should be pressed again. Or ask a professional for a design (based on generic requirements, no fixed determinations!).
