P.S.
As far as I know, the OP didn’t write anything about his provider?
"Nothing" is relative, by the way, otherwise I wouldn’t have immediately known who the builder might be.
The OP wrote that the company has existed for 30 years and carries out about 150 constructions annually: in the threads where he wrote that, you also participated, by the way.
If you, like me, know "a bit" about Oldenburg, you know at once that, based on this data, only one company is actually possible. And as was clarified via PM (the OP sent me a PM immediately with the name), I was right with my guess. :)
But I still don’t understand what your problem is...
Exactly – as I replied to you in the mail, you will have to be a little patient.
Right, but try telling that to Bauexperte, because he asked me why I didn’t register there… :p
