Hello,
I am not very familiar with "landhausoptik," but do you have to install such small windows for this look? If you enter your house from the north, you face a wall. Because of the small windows, this hallway to the kitchen will also be very dark. That doesn’t seem very inviting and shouldn’t be necessary in a new building. Why don’t you make the entrance to the living room straight ahead, so light from the south side also reaches the hallway? Why are you planning this corner bench in the kitchen? Will there still be a "real" dining area in the middle of the living room? You don’t want to sit on a corner bench with guests where everyone has to get up if someone wants to leave the table, do you? Children only play in their parents' living room for a very short time; after that, you hardly see them there anymore :) .
Best regards
Sabine
