Modern glulam buildings (or if you are in EU gablok could work) or masonry, pluggable plumbing and electrical (see Swedish prefabs, they use a pluggable electrical so you plug one wall into the other, wiring is embedded at factory), metal SIPs roofing. You can get pretty close to this with current materials.

That's pretty interesting and while I sincerely hope it works as advertised, what is the repair process when (not if) the connections inside the wall fail? As the owner of multiple homes, a part of me is very skeptical that those connections will last for decades untouched.

In the US, code does not allow for splices and connections inside walls, period. In a pre-fab, I would like to see all of the cabling run inside tubes so that I can fix/add/replace easily myself in many years down the road. This is prohibitively expensive for residential mains wiring but not terribly unusual for low-voltage stuff like coax and ethernet that the homeowner can do herself.

All cabling is in conduit, so if it fails you either fix the gang box if that is where it failed normally as you do in US. If the wire fails you replace it by pulling it through the conduit and fishing in a new one. It's actually a fairly decent setup compared to our standards. They also typically use a installation layer, which is a furring wall where they run these cables, meaning you don't need to mess with vapour barrier.

how is pluggable electric in conduit is going to work in prefabbed walls? you pull all wires through preinstalled conduit during wall placement?
