What I notice: do you really want such a large sink with a draining area? That would cost me too much workspace, and with a dishwasher, you actually don’t need it. Also, I would swap the stove with the sink; you use the sink more often than the stove.
I would also strongly recommend a children’s bathroom. Is one of the children a girl? And does she always pass by mom’s dressing table when she comes into the bathroom? Well, I know how that would end with my niece... Mom wouldn’t be happy with her makeup utensils anymore (if they were still there). And personally, it would also bother me if the kids are always fussing around my back when I want to put on makeup in peace... Think that through again.
I don’t find the door directly into the bedroom so disturbing. The one who goes to bed later or gets up earlier will go through the bathroom anyway. So you can do either way, I think. Okay, if the bathroom would then only be accessible through the dressing room, then move the door from the bedroom into the dressing room. Then definitely! I would rather put the door between the bedroom and the dressing room and leave the dressing room open to the bathroom (I don’t quite remember, but you have controlled residential ventilation, right? Then humidity wouldn’t be an issue). As I said: the one who is already sleeping or can sleep longer will also be disturbed by the rummaging in the dressing room.
I would cancel the open space – it’s too small to really have an effect and only transmits noise from below to above. So if the teenagers have a late-night TV session or the dear husband wants to watch a boxing match from the USA live, you will hear it directly in the bedroom. Just to have the trendy open space here that has shrunk to a tiny size? Not worth it for me. Close it off, keep the floor-to-ceiling window there, and have a bright, spacious hallway. Maybe you can put a Vetsak there and create a reading corner or let the kids set up a Carrera track there (and dad) or something.
