The house was extended by 1 meter because it was a bit too small for us. Somehow we rejected that idea because the children's room is right next to the living room, so there is no quiet area. The living-dining area was too small for us. We will dig out the design again and see if we can swap the child and parent rooms.
The curve at the bottom right of the plan is unfortunately not so good for the layout. You have to keep a 3-meter distance from the edge, so the house cannot be made that wide at that point...
