I have roughly sketched everything out. I'm at the point where no retaining walls are needed anymore, I will upload that tomorrow.
I am not yet that far with the room concept.
It will be similar to what described.
How many KZ should there be?
I have now planned 100m2 per floor. approx. 150 m2 living space 150* 2500 Euro = 375,000 Euro + garage 35,000 Euro
2 children's rooms, bathroom, entrance, hallway, wardrobe, utility room, basement, etc. in the basement
Living room, dining room, kitchen, bathroom, and terrace on the ground floor
Office in the attic
