Jointing for cladding is wavy / uneven

Hello,
unfortunately, the surface in our new building looks very wavy and radiates a sense of unrest.
Normally, we only know of flat and smoother finishes.

Is this a defect and can it be fixed?
Otherwise, can a deduction be enforced because of this?

Thank you very much for your assessment and best regards

In our new build, the coating unfortunately looks very wavy and radiates a sense of unrest.

What you describe, I honestly do not see. I only see in the second picture that it is a bit untidy and needs to be wiped again. But it is also not finished yet.
Is that the Viebrockhaus?

Actually, I can also see a very "uneasy" pattern. But not only in the joints, also in the stones. I mean, they are set very untidily just as the joints are filled untidily (all my personal perception). Whether all this is within the permissible tolerance, of course, I do not know. But: money does not make the joint pattern calmer!

Below the windowsill not nice. In my opinion, but very low chance of success for complaint.

As writes, it is probably an interplay of "crooked" stones and the grouting, which was pressed in more strongly at the top and bottom. Yes, it is Viebrockhaus. Why?

Yes, it is Viebrockhaus. Why?

I have "only" guessed based on an indication and it has nothing to do with the execution :)
