What do you find so convoluted about the upper floor?
Yes, I would say it like this:
- Child 1: 6 corners
- Child 2: 6 corners
- Guest: 6 corners
- Anteroom: 8 corners (without bay window) and very large, with 20% of the floor area
- Dressing room as a passage room without windows. Only 1 meter passage between wardrobes, therefore only sliding doors
- Children's bathroom: passage in front of WC only 0.5 m to the shower.
In my understanding, you tried to fit too many functions on one floor (dressing room, living anteroom, 3 children's rooms, 1 master bedroom, 1 large bathroom and 1 small bathroom). As a result, you have to make compromises in every room and lose a lot of free movement space.
