Renovation of old building floor plan division - kitchen solution sought

We want to replace the bathroom with a shower, redo the kitchen with more workspace and as little through traffic as possible across the kitchen area.

That's basically everything on the ground floor. In general, however, we are also open to more radical solutions (removing the wall to the dining room or similar).

The changing benches are kindergarten furniture, they make everyday life much easier ;)

I will compile and provide the plans.

Attached is the complete ground floor for Var 1 and Var 2.

And the original once again next to it and because of the cars and paths the site plan wouldn't be bad either. You always need everything...

Attached is the site plan, it concerns 116/2.
Additionally, the two variants + original

Where do you want to make the terrace? In front of the children's room?

The terrace is already there, yes. You can see it quite well in the pictures.

Currently, it is a children's room due to lack of alternatives. Previously, it was a study / garden room and we will use it that way again after the renovation, since my wife is a teacher and accordingly needs a lot of space in the study.
