I wonder if many have seen just how fast the factory-build house market is progressing. I saw a neighbour's wood-frame 3-story house erected in a day using a giant crane, complete with internal wiring, plumbing and decoration, and that was over 10 years ago! Course, they then had to connect to all the external utilities, and put on a brick outer shell and the proper roof. But it was pretty amazing.
I'm not a fan myself - my place is over a century old, and I wonder if the internal structure of these new houses would last that long. But they do show what is possible. The 'housing units' in the vid cannot be compared to regular houses, whether European brick or US wood built, but the design and engineering is pretty amazing, and show what's possible for fast erection of temporary housing.
My view - in the future we'll see a lot more of these. They could even form the basis of a new kind of traveller lifestyle ... for better or for worse ....
