The selective measures are not the all-in-one package but the inspections planned according to my wishes. But well, maybe yours is simply closer and therefore you save travel costs and time.
Without Vitamin-B, I consider 1500 to 2000 euros for the expert companion to be significantly underestimated (I would plan for 5000). There is IIRC a thread somewhere here with a concrete example.
My wife and I are planning to build a house..........

House connections €7,500
Rainwater €2,000
Building permit €1,000
Surveying €2,000
Building expert €2,500
Construction water €1,000
Construction electricity €1,000
Building insurance €500

Which items are missing or need to be adjusted?
Thanks in advance and best regards

The item for financing costs during the construction phase / and possibly double burden due to rent and interest is missing (if you finance part of the house with a loan). That quickly adds up to €3,000-4,000!
