Regarding the measurements:

The separation between room 2 and 1 is a step, not a wall.
Between room 1 and 4 there is no wall; I didn’t know how to draw it differently. It is a small open hallway with an entrance door. Room 3 is the spacious guest bathroom.
The water connection is currently located under the window and, after consultation with the installer, it will be moved because I want to swap the sink cabinet with the dishwasher. This way I have more space at the sink and no possible obstruction at the tall cabinet/fridge. It will look approximately like this:

Yesterday I read some interesting articles about "Dead corner = Good corner". Now I am considering whether to "let the corner by the dishwasher die". That way I would still have a bit more space on the kitchen countertop itself. We have plenty of space for pots and pans.
The same applies to the U-piece ... I think, as mentioned above, it makes more sense to install a 60 and 40 there. Especially since at the right corner there are only about 35 cm that I might lose.
