I would have liked 300-400m2 more garden back then, but that is no longer affordable.. in 2014 it was already 80000 euros more.
Then a flat roof overhang at the children's rooms that would be used as a balcony, and 1 meter more in the kitchen. But roughly 30000-40000 euros more.
The rest were fantasies like e.g. air conditioning in all rooms, a pool, but otherwise actually very satisfied.
