So, I am against an open kitchen. So if someone is vegan and eats yogurt followed by arugula salad in the evening, well, they can also have an open kitchen. But if mom is cooking hearty meals, the Christmas baker is busy, and traditionally everything happens in the kitchen, then the kitchen area should be kept closed.
The grease and moisture spread throughout the whole house. And not even a Bora helps with that! It always depends on the size. But nowadays people cook much less. Deliveries like Lieferando are more common.
We have about 30 sqm of closed kitchen, a large table in the middle where we also eat. The terrace is connected by two doors. In summer everyone sits on the terrace anyway. Then carrying everything through the living room is also annoying.
You also want to feel warm sometimes. In the dead of winter, it can be 25 degrees in our kitchen. I wouldn’t want to miss that. And keep one thing in mind. You get older. And the older you get, the more susceptible you are to drafts, to cold in general, etc. At 30 you don’t notice any of that. Heating the whole house to 25 degrees is just not possible technically nowadays.
I know people with open kitchens. They actually have their cooking kitchen in the basement and it’s connected to the upper kitchen by a small elevator. There you never have pots left standing around or a dirty stove.
