In my opinion, that still contradicts itself. Why have a 2-room apartment for the parents if they are not moving in yet? In the end, they will never want to leave their house. Then you have completely wasted money and space.
then you wouldn’t have sunk a quarter of a million but “only” an eighth of a million... and in the event of needing care, they would probably appreciate the ground-floor apartment more than the stairs to the attic. And what exactly is a person in need of help supposed to do with 120 m2?
Thank you very much for the Norden
However, I do not understand why the house is being pushed to the western boundary instead of orienting a slightly narrower house, mind you rectangular, on the east side.
