Attic floor room layout - We're running out of ideas...

For a child, I would skip the children's bathroom, plan a nice family bathroom and a proper dressing room

If I'm not mistaken, the 2m limit at 38° is relatively close behind the wall (about 15cm)? I would only swap the bathroom and the bedroom. Just need to check if the water disposal works through the study. The kids' bathroom also has to connect somewhere. Whatever the architect planned there, maybe it can all be routed downward together?

The children's bathroom is in a dire situation: the sewage disposal is pretty much dominant in the dining area. Or between the living room and the stairs. I don't understand the orientation of the house on the property. Entrance in the south, garage in the north... and where is the privacy in the garden? The street is in the north? And how does one, for example the postman, get to the south entrance? I know this is not supposed to be discussed here, but I am curious.

I was also very surprised about the orientation... in autumn, the living space will probably be pitch dark, I think? Not much light comes from the west anymore. Is the roof extended so far to the north? For what purpose? Sun protection can't be the reason, there is no sun there. That's exactly why I would design it as open as possible to capture the light that is there.

You don't have to respond to this, I just wanted to provoke some thought.

I just realized I have the cabinet spread over 1x 3m and 1x 2m, which makes 5 cabinet meters. Or do you actually have a 4m long cabinet now? I’m afraid that one won’t be moving with us.

Swapping the rooms is one possibility. Only the bathtub should preferably be a straight one, not a corner version. But maybe that can still be arranged. The drainage could then really possibly be routed together with the kids' bathroom from above through the study??? Better than through the living room
Luckily, I don't have a 4m wardrobe, your planning is fine as it is kaho674
Regarding the orientation, I just made a "breakfast sketch" on the table, please don't stone me
I hope it's recognizable like this.... a view from above. Due to the building window on this corner plot, no other orientation is possible given the size of the house. This seems to be the best option.
