Initial floor plan on graph paper: slope, basement + 2 floors.

Even though it was not received as well here anymore, the floor plan from #59 remains.

So not in the compressed version from post #60.

So not in the compressed version of post #60.

No! Silence has been agreed upon regarding this. ;)

Will it then also remain at the calculated costs?

Do you still have buffer? Many surprises are yet to come until the outdoor area is finished. Which [GU] are you building with?

Will the calculated costs remain the same?

Yes. :)

Which general contractor are you building with?

Yes. Especially because the point of support measures was planned "as precisely as possible," but of course not definitively. We have included other things like kitchen, outdoor areas, paving, terraces, and incidental construction costs. What other surprises are you thinking of?
We decided on Brandl Bau.

You don’t hear anything bad about Brandl here and many people build with the company around here.
So much more came up. The first was the structural engineer. The one who was involved from day one.
New soil report, another 3k gone
Retaining wall thicker, reinforcement (quote from the construction company for earthworks "Is he afraid of Kim or why is he planning a bunker? Crazy") thicker ceiling etc. five-figure plus
A wall there, a bit more excavation than planned there, material missing again there.
Then you talk to the craftsmen and change things during the construction phase. That’s the typical small stuff that has been worth every cent so far.
Oh yeah, and that you’re talking past each other. Grading of the driveway. It seemed a bit cheap to me anyway, who comes up with the idea that the one building the garage offers only a 20cm gravel layer 1.2m above road level and not the backfilling.
