Financing offer for our construction project, ok?

What I notice:

[*]Actually, no one gets by with the construction service description, how about a buffer for sampling? Whether it's more sockets, etc.
[*]Are costs like flooring, painting work included?
[*]Will you manage with €1,500 for furniture? A few pleated blinds and some cheap bathroom items and you're already at €1,500.

The construction service description would be adjusted according to our wishes. It also includes the floor coverings, painting work, etc.

Since we have sold a house, we only need small items which I have summarized under the item furniture. Otherwise, everything is available.

Well, a 2.7% buffer is really nothing. Especially the incidental construction costs seem to be more than ambitiously estimated (in your other topic, I believe 7,500 of that were already for the connections). But refinancing 15-30,000 is no big deal given your starting position.
