Living room floor plan ideas?

Alright, here now something a bit more professional than before. My question: can I fit a half-turned staircase in there?
And am I overlooking anything....problematic corners?

Oops.....what happened there? How do I upload that sharply?

Dressing room and K1 are junk... say goodbye to the dressing room... you sacrifice the children's room and then have a dressing room with a 60 cm aisle... (my opinion at least).

I would now have an architect draw it. They have an eye for that. Take your floor plan with you and explain to him what you find problematic.
