Floor plan design of living and dining area on 30 sqm

Sorry, you are right I did not respond to that. We are 2 people.

There was already a comment in this topic that the jackets are hanging almost in the kitchen and the position of the [Garderobe] is therefore not optimal. That is why we considered making the hallway wider and thus also getting a little more distance between the kitchen and the [Garderobe].

If there are only two of you and you are disciplined, a small cabinet/wardrobe is enough.
You still have spare rooms, the use of which is still open.
It is not ideal, you know that yourself. But making the kitchen and bathroom smaller because of this now, I think, is the worst solution.
How about making the wardrobe cabinet out of the kitchen furniture? So the same decor, three 60 cm units: that visually elongates the kitchen and integrates it ;)

It is about moving the wall of the kitchen and the bathroom so that it aligns flush with the pillar.

Regarding the kitchen, I already advised this in post #14, to create a wardrobe niche. As for the bathroom, this does not work because then the shaft would be in the hallway, and the bathroom door would push the sink user.

Maybe I’m missing something, but where would the wardrobes be in that case?

Yes, I remembered your suggestion. In fact, the bathroom was originally planned as I drew it in the exposé. We then moved the wall to get a slightly larger bathroom. It’s unsettling when you read a lot here in the forum and see big houses and the criticism of their layouts (usually too small entrance areas). Of course, you can’t compare that to a 75 sqm apartment, but you question every centimeter as insufficient. I thank you for your feedback. I will soon plan the ceiling spotlights as well. I will get in touch again then.

maybe I'm just missing something right now, but where would the cloakroom cabinets be in that case?

In these cloakroom cabinets that pick up the design of the kitchen. The rest in your hobby room :) Where? Either where marked or above the pillar. Both have different spatial effects. Cabinet on the right side hides the hallway, making the kitchen bigger. Cabinet above the pillar narrows the kitchen and focuses the entrance.

Which size (and drawing) "is correct" now? - don't forget: in your apartment you may be able to move things around, but not the shaft that runs through several floors.
