I only partly agree with you. What is really good is the balance between parents and child. Many have dressing rooms that are bigger than the children's rooms.
Nevertheless, overall it is unbalanced. Mini-flat, oops in the basement there is a frying pan handle left = sqm waste, upstairs you run into a wardrobe in the master bedroom (this also happens to some with 25 sqm) and with the choice of beds you are also limited. It feels like a bungalow where you are forced to shove a basement underneath, in which you just cram the perhaps necessary children's rooms, an apartment for subsidization, and a huge, jagged basement room as the leftover piece. Even the children's room gains enormously if the door can be moved 60 cm towards the pantry. Why is the pantry so far away?
What happens? As long as the children are small, the kitchen in the apartment is used more than the main kitchen upstairs. Child 1 is rocking, Child 2 needs a fresh diaper, both children upstairs because the diaper was forgotten. No, we can't go to the garden to play now, the cake has to come out of the oven in 12 minutes, etc. In the evening there is a barbecue invitation. In addition to the normal seating set, a beer bench is also used, it gets too tight at the grill, so everything goes down where there is space.
