extend the office upwards according to the plan, then it fits better. Otherwise, you have too much dead space in the open area, and I am a fan of plenty of space ;)
As a layperson, I would describe the entrance as "meh": as a visitor, the first thing you see is the staircase going up, the cloakroom is 2 meters away from the entrance, also past a door that is not intended for "visitors." And there is much unnecessary space as a passage to the all-purpose room. I would probably try to swap the WC and the cloakroom somehow and make the cloakroom large and above all usable enough. Are the windows in the cloakroom floor-to-ceiling?
as much glass in the living space as in a greenhouse, even more glass because of the bay window, from Easter to October it is a greenhouse and the shading is in constant use, no one can stand it without air conditioning, and the view from the sofa faces the only wall, I don't understand it

When I see the furnishing here: sofa in front of the (floor-to-ceiling) windows: relatively suboptimal. Then I would put the toilet on the left (where the wardrobe is) and the wardrobe on the right (where the WC is). That should actually work.
