I will never understand why we fill our walls with mechanical and electrical infrastructure and then wrap them in a paper and plaster, which then needs to be torn, broken, and repaired in order to maintain said infrastructure.

Pipes will fail. Wires will fail. Ducts will fail. Maybe not in 5 years, but over the span of 20, they will. Why make them so frustratingly inaccessible?

Drywall is trivial to remove and repair, I have no issue cutting walls with a circular saw or vibrating cutter to get access then patching it.

I have seen another method for making walls that were accessible though, from a homesteader/ hand tool woodworker and carpenter. His walls were 24” thick with huge areas for piping and electrical and had 4x4’ removable wood panels.

What's the alternative, though? Removable panels will be more expensive, and troublesome in various ways.

Drywall is not too bad to deal with. And 99% of the wall surface doesn't need to be opened for a -long- time.

If we ever build another house, it's going to be attic-free with exposed conduits + hvac ducts / pipes on the ceiling. Every electrical box is going to have a 2" conduit (embedded in the wall) running up to a conduit that runs on the ceiling (if there's a basement, then down to the basement ceiling).

This would let us avoid stapling electrical lines + network cables to studs inside walls. Fixing shorts, adding circuits and upgrading network lines would be trivial.

We'd have to buy what, 1000' of conduit? There's no way that's a sufficient fraction of the cost of a house.

Rarely do pipes, wires, or ducts just outright fail even in 50 years. Usual case for tearing out drywall is for voluntary renovations. Shit behind the wall just doesn't "fail" if it is left undisturbed or you were unlucky like those that got defective PEX or similar installed.

The paper is a critical technological innovation. It shrinks upon drying, turning the sheet into a prestressed panel. Predecessor manufactured wall materials like Beaverboard are much flimsier because they lack a taught skin that enhances rigidity.

I wouldn't call it easy, but it's conceptually simple to cut a square hole in some drywall to access behind it, and then pop the piece back in with screws, mud, and tape, then paint.

And do what? Leave the ducting, pipes, and electrical lines exposed for the one time in 20 years you need to do something with them?

In addition to being much more attractive than exposed infrastructure, drywall and the insulation that gets put behind it help make your house much more energy efficient.

Cheaper than building them behind concrete or brick.
