Thank you very much for all the responses here. I hope that the discussion also helps other homebuilders with their decision-making. To be honest, there was no answer for us that clearly dissuades us from an open kitchen. One has to say that open kitchen is not the same as open kitchen.. As already written here, there are many variants. Therefore, we would like to use the dynamic of the discussion to get feedback on our considerations (especially from the advocates of the open kitchen).
There is option 1 with an open kitchen including kitchen wall:
Advantages: A door in the hallway is possible. Guests do not see the kitchen immediately when entering the living room. View axis from living room to kitchen is more limited.
Disadvantages: Less ergonomic Smaller wardrobe than option 2 Smaller pantry than option 2
In option 2 the kitchen wall is removed:
Advantages: "Clean" matter: Less corners and edges than option 1. Probably even easier to keep tidy and clean than option 1. Larger wardrobe + pantry possible (yes, for some the pantry may be oversized, but for us optimal). Representative kitchen (although that is not so important to us). Even higher sociability factor.
Disadvantages: Very open design that we might regret due to cold drafts (when the outer door opens) and noise ambiance. Every guest first walks past the kitchen and possibly sees the mess.
What do you think? Have we forgotten something essential? Reason says option 1, heart says option 2 :)
