Construction costs are currently skyrocketing

Peter Lustig is really funny. He certainly has a certain entertainment value - despite all the cheese that is written there. But Peter Lustig just likes to explain the world to the children.

Even 30 years ago, no one would have thought of building turnkey. That would not have been possible cost-wise at all.

I once saw a documentary of a turnkey house from the post-war period.
In 2021, a Qelle prefab house from the 60s was relocated to the Kiekeberg Local History Museum: back then, you could order the prefab house not only turnkey but also with matching furniture and curtains.
The prefab house world invented the turnkey house. This includes, among others, Okal Haus, Budde, Hoesch-Haus, all from the 60s.

Let me calculate: turnkey house construction has turned 60. And through prefab construction methods very attractive, since cheaper than solid construction.

Let me calculate: the turnkey house construction has become 60. And very attractive due to the prefabricated construction method, as it is cheaper than solid construction.

… back then. Back then it was cheap and very attractive, especially since it was considered stylish to order something and not have to get your hands dirty.

I think more of Captain Blueberry and his grandchildren, sailor's yarn, fed from dubious sources ;)

I can only say, my parents built a turnkey house 41 years ago ... and they were not the only ones ;).

My aunt ordered a turnkey house from Neckermann almost 40 years ago.
