Total cost for a 190 sqm house (flat plot, without basement)

What are grounded graphite plates good for?

Take a look at the electrical system and the outdoor water taps

Could be roughly right, we don't know your requirements. With blinds all around, 90x90 tiles, Q3/fleece, and a lot of lift-and-slide glazing, every house has still been expensive. Kitchen for 12k should not be a huge problem if we are talking about 10-12 sqm Schüller/Häcker/Nolte without luxury price drivers.

Smart minds here take their new expert for the first time to review the construction service description and the contract. He indicates where additional costs will arise.

Yes, that's exactly what we plan :)

Graphite plates serve to shield against electrosmog (similar to carbon and copper).

What also falls under "non-standard": double wall between practice and living area on the ground floor

Thought that's what Katja is for

Then you also don't have a microwave, no Wi-Fi, no mobile and cordless phone, no devices on standby? I lack the discipline for that.

Obstlerbaum is right, you pay a lot for every house. I would still look closely, not everything is run-of-the-mill. I don't let anything happen to my Schüller kitchen.
