Hello,
And just mention that there are also providers who offer turnkey homes, although not many.
That is not quite correct ....
Basically, the circle of providers – probably without coordination – has agreed to offer homes without painting and flooring and has documented this in their respective BB. On the one hand, this is due to the fact that the vast majority of builders prefer to carry out these two trades themselves; on the other hand, of course, it also makes the offers look "friendlier." I know only a few exceptions among the providers (through my "side job") who refuse, upon request, to include these trades in their offer for an additional charge. Mostly, the offer can be extended to include these works.
Rhenish regards
