As already written above, we are currently considering intensively what it would be like with an open kitchen.
The kitchen question has already been discussed extensively, but it is not just black and white here either. You can also visually divide it to separate the areas a bit and still maintain a sense of space.
A very successful example from recent days see:
Or these oversized "pass-throughs" that were popular in the 70s, etc. Or partially glazed (a colleague of mine placed these industrial glass U-profiles vertically), etc. Or you put cooking/dining on one side of the house, living on the other and in between the hallway with an adjacent office or similar (that's how I had it in my previous old apartment). Just as a suggestion to cause further confusion
