Floor plan optimization living area

Only one ceiling per floor height is taken into account for each floor. The floor structure is not drawn, so the room height is later calculated as 2.6 minus the floor structure.

And has the building application already been submitted?
The static calculations are attached to it as well, right? Even if your shifts are possible, it will actually get tight in the kitchen. Also, the table will then be in the way.
Options, without having pencil and paper at hand right now, I see either if you move the stairs to the left side of the plan, which affects the lower floors, or stretch the kitchen upwards on the plan, pantry where the guest WC currently is, and move the rest as well, so that the living area gives up some space. So a rotation counterclockwise.
Take a look here: with the chimney flue and the doors you have to find a compromise... and additionally the WC window, something like this

But that means the room height will then be 2.4 m on the various floors.

Only the wall next to the staircase on the right is load-bearing.

What kind of comedian is this architect that he plans these fantasy dimensions everywhere? – he should have understood from his profession that this unnecessarily creates stone cutting or botched jobs.

Besides, I wouldn’t have the wall alignments continue monolithically into the window reveals anymore, but rather set wall sections one octameter wide there (or in Bath2 even two octameters wide, otherwise the reveal is isolated compared to the partition wall). I think more and more young architects nowadays have never worked practically on construction sites. But at the very latest on the drawing he should see this crap!

But I left them like that!

Which spots do you mean exactly? Living and dining rooms?

Are you generally talking about the distance of the windows
