Far too little information! And 2500 euros per m2 should already include something special, including a bus and unusual architecture.

Much of this does not belong in the house price calculation

Yes. That is correct. Maybe I chose the wrong wording. What belongs in the [hausplanung]? Then I can standardize and compare the values.

Well, only what concerns the house. Without garage, exterior, fireplace, incidental construction costs, etc.

You will probably end up at about 1700-1800 EUR per sqm. That is very realistic. Just nothing special, but "normal" standard..
