Of course, it is not the absolute truth. We are here in a forum where it is about opinions and advice. I am retired and therefore I have dedicated a lot of time to the topic of house building and have followed quite a few house builds out of interest, about 15 in my circle of friends and neighbors, and even before choosing my own provider, my wife and I have repeatedly visited, of course under different names, all prefab house providers in the prefab house parks in Fellbach, Ulm, Günzburg, and Karlsruhe. In general, they are simply too expensive for such a papier-mâché house. I have created a list with all providers. The worst for us were Danhaus and Scanhaus Marlow Marlow. The assembly goes quickly but the delivery time for example with Schwörer alone is also 2 years. I would rather build solidly for 200,000 euros with Heinz von Heiden, and invest what is left into nice upgrades of the house and sleep well because the mountain of debt does not weigh on me, than for example a house from the prefab builder Schwörer for 400,000 euros, uncustomized, just the basic house. Small regional construction companies are also not bad. They score clearly through much more customer service. But they cannot keep up in terms of price by far.
