After 3 meters, the wall in the bedroom does not look like that. And where is it not practiced, those who do not have a dressing room: one meter for the man, one meter for the woman, and one meter for the family (Bett- und Tischwäsche)?!
Hm... We currently have a wardrobe of 2.5 meters and a separate dresser for towels and bed linen... So far, that has worked out pretty well. We might possibly get bed boxes for bed linen.
But I can already tell: I really thought at first that this was a very generous floor plan... Hm.
We are currently building a gable roof house with 150m2. We chose an open kitchen, but the rest is okay with 4 well-proportioned rooms. One of them we use as a study and guest room. The attic is then my hobby room or study if child number 3 still comes. Since the door to the kitchen on the ground floor is removed, we have space for a larger wardrobe and the guest bathroom with shower is small but okay. I believe our traffic areas are significantly smaller
In any case, you should also consider why a dining table only has 6 seats. We are planning space for well over 10 people, because in everyday life you will eat in the kitchen and if a second family visits, you will be about 8-9 people. Then the mother-in-law will have to stay at home
