Nothing is really transparent there. It clearly runs according to the motto: No idea how it works, but it works. The business model is based on a so-called maximum price, which can be undercut but not exceeded, as long as you stay within the framework set by Ecki. If you are looking for the 100% (legally) secure option, you are in the wrong place. But you probably won’t find that anywhere. DHI’s good reputation is not without reason. In Saarland, it basically runs on a basis of trust. The contract’s audit result would not please you.
So far, there is nothing negative to report from our side. DHI takes great care. Unfortunately, construction was hampered by the weather. The windows are supposed to be installed on Monday... I hope so anyway.
And yes, drywall partitions are cheaper. Counterquestion: Where do you see advantages in the solid walls on the upper floor?
Regarding RKR, I say nothing. There is currently a blog running (can be found on Google).
