Why is the window on the east side so low?
The basement is okay
What kind of staircase is that? (rise)
Unclear if the bathroom drainage causes problems via the kitchen
Reevaluate the gallery - now a good half meter is lost there and the roof shifts, right?
Don’t underestimate the noise transmission through the gallery... I would seriously consider whether to leave that open to the downstairs. Do an experiment and put a TV in front of the children’s room and see what you can still hear inside.
People can look into your bedroom from the street, right? Unclear if I would like that.
I would also question the north child room. Possibly swap some things around. Children’s room 2 where the bathroom is now (move the wall so the two children’s rooms are the same size) - bedroom where children’s room 2 is, keep the dressing room, bathroom where the bedroom is.
That is already an extremely large dining and living room (which you notice somewhat from the different furnishing) - including the kitchen it is then 74 m² ... I find that a bit over the top ... but okay, if you have enough money.
So far, best regards
