Looking for a floor plan decision helper

At least the entrance area should definitely be widened again to a proper width where you can turn around without any contortions. The kitchen with 289 is not exactly the narrowest, too narrow would be 220... However, I doubt that this drawn kitchen can accommodate everything. In my opinion, there are not enough cabinets available.

The decisive factor is not the square meters, but how the space can be used. The question is also how your kitchen should eventually look - the wider version of your neighbor could be quite unergonomic/ with many walking paths. In your narrower version, a two-row variant with better spacing can be implemented; whether an island still has space (if you absolutely want one) is questionable. So you should definitely think about how the kitchen should eventually look.

In the planning, I would also seriously consider whether you really need two doors right next to each other; at the moment, you are not saving any walking distance but are taking away storage space. Possibly, instead of the kitchen door, you could plan work surfaces/ tall cabinets there or at least move the kitchen door much closer to the front door (then possibly an L-shaped layout on the bottom and left walls of the plan, tall cabinets on the wall towards the hallway - this also saves a dead corner or a more expensive corner cabinet).

Isn't it unusual to end up in the kitchen from the hallway instead of the living room?

Actually, yes.. but with you, you would already look into the dining room with the door half open.. I'm not a fan of slanted walls...

Thanks for the suggestion!
Hm, isn't it unusual to end up in the kitchen from the hallway instead of the living room? I need to think about that again.

Is unusual necessarily worse?
