Well, the vast majority of Europe builds concrete homes. We definitely get insulation, internal plumbing and wiring.

Individual homes in Europe are typically built from bricks, with concrete used for foundations/floors/ceilings.

The work around internal plumbing and wiring is messy, though. A lot of abrasive brick dust is generated. I wouldn't want to be the guy doing this stuff. In a 3D printed home, nice empty spaces could be left in the wall while printing for all the necessary networks.

In modern european homes, plumbing and wiring is done via "octopuses".

Most of the time, every connection coming from the exterior are coming through the floor in a little room that we can use for storage and from there, everything is dispatched through inner walls which are basically empty (except around bedrooms if you want acoustic isolation). This allows to maintain everything from the inside.

I wouldn't call it a mess but I'll acknowledge I'm talking about modern constructions.

I was just watching the construction of my new home and they drilled into the brick walls all the time. [0]

None of the walls were empty, all were solid brick with no empty space.

It was quite a mess, though the guys doing the job were very professional and handled the dust disposal very well.

wow ! In which country are you ?

I've never seen something like this in France.

The Czech Republic. I have seen this in all homes under construction that I saw, except for wooden ones.

Granted, it is a small set, N < 10.

I didnt noticed that it was a picture of your inner walls. In France, we only use bricks/concrete for the structural walls. The inner walls are almost always "placo" mounted on steel rails.
