Just as I had to make the kitchen a bit narrower because the space between the work areas turned out to be way too large.
My words ... when it comes to 2-line layouts, 280 cm room width is too much.
I like it. And, for the "spontaneous cloakroom" one could simply consider accessing the storage room via the bathroom. I wouldn’t find that too dramatic.
And the door between corridor/kitchen could still be executed as a sliding door running downwards in the corridor according to the plan.
Possibly make the kitchen window so narrow that on the right and left there is space for one tall cabinet each, so roughly 70 cm of wall on both sides ... the right side already has it.
Then in the kitchen, from the top left, you could actually plan ... oven tall cabinet ... secondary storage area ... and in front of the shaft a tall cabinet shortened in depth for standard pantry items in the kitchen. In the niche below, a standalone fridge that then transitions into the sink line and on the right side along the outer wall the cooktop line ... where exhaust could possibly work well.
That would be my spontaneous kitchen plan, which is rather spacious without tall cabinets toward the bottom of the plan.
