Is this secondary construction cost calculation realistic?

Then 1500 EUR/sqm is very cheap. Congratulations

We were at another Gu today and during the conversation also prepared a statement of additional costs. What do you think?

Fits except for electricity and water, but at least for us that was peanuts, altogether under 500,- Surveying for the cadastre was a bit more expensive, around 1100,- A soil report was not required here at all, but since there was one, he took a look at it. Karsten

But what are we comparing? Kitchens, painting, lamps, floors, beach chairs, geraniums, lawns, sheds....all part of the house, but not part of the [Baunebenkosten]. These are indispensable, whereas theoretically, one could live for a while just with a microwave, kettle, and a 120 Euro sink.

I am concerned with the specific additional construction costs. [Küche] is excluded. [Carport] and [Terrassenüberdachung] as well. Because these are costs depending on taste and requirements.

For example, I don’t see anywhere where the connection of downpipes to the rainwater shaft is addressed.
