Ctrl F "brick". Nothing about bricks and concrete in all the history of wall surfaces.

Brick is mentioned near the top: > a method of constructing walls that has been a mainstay for at least 6,000 years, predating mud bricks To be fair the article is about drywall and its history, not the history of all walls in general.

I was thinking of fired brick and concrete, which solves much of his problems of drilling into walls.

I think this misses the beauty of a plaster wall. Level 5 drywall has nothing on a skilled artisan with plaster, and yeah you can’t hang things through it but it also lasts hundreds of years. My walls are 120 years old and robust, the kids haven’t damaged them and they’ve more than held up.

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?

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.

No -- use doors.

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.

I watched a video recently, which I can't find, where an architect set up a beautiful wooden baseboard around the entirety of their property, and that baseboard held all mechanicals and was perfectly clean and easy to get into as needed. Drywall is manageable and cheap, I agree. But it's more painful than it should be for something that _will_ require maintenance.

This sounds great but violates all the building codes for a variety of reasons: eddy currents, risk of electrocution if there’s a short somewhere, noise in telecom cables, etc.

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. https://youtu.be/8fdm9R1Cbm0?si=9SRXgcdutos-h…

It's the repainting that bothers me

I think the question is: why are they behind anything to begin with? Conduit all the things and paint to match?

Probably not legal.

Generally things that are illegal are illegal because enough people have maimed or killed themselves with it in ways that are not “common sense”. For example, you can’t simply have electrical wire stapled to the bottom of the joists in the basement because people might try to hang clothes off of them.

There are reasons not to like gypsum drywall:

> Some buildings standing today still have wattle-and-daub panels from 700 years ago.

Will any drywalled building survive even a tenth of this time?

> The plaster mixture used then was a homegrown concoction, with recipes matching the climate needs and vernacular material availability.

The wonder of wattle-and-daub (clay) and plaster-and-lath (lime) is that the materials are breathable, move with the structure, and can even self-repair small cracks. I don't know of any old house that suffers from black mold...

My last big gripe with gypsum drywall is disposal. Demolish a property with clay or lime walls, and they'll naturally degrade into the environment. Drywall needs proper disposal: "Do not burn: Drywall releases toxic fumes. Do not bury: It can create dangerous hydrogen sulfide gas in landfill."

Does anyone want to live with that?

I wouldn't call it trivial. First you have to determine where to cut it; if you cut the wrong area you have to cut again. All the steps in repairing it either take time, are messy, or require some skill, and the time adds up (e.g. waiting for the patch to dry before you can sand; waiting for the primer to dry before you can paint; etc.).

And then you have to match the surrounding paint, which is all but impossible since even if you have the same color, the original will have likely faded over the years, making your newly applied coat a mismatch, so now you have to paint the entire wall (no fun when it's a big wall). And if you had wallpaper instead of paint, good luck to you unless you saved some extra scraps.

All in all, an access panel would make the job much simpler.

You don’t need to explain that to me.

Interesting to me that no mention of the use of drywall (in various forms) to act as a substrate for actual plaster. This seems common in the UK from what I understand from my family back there, and it is also common in the USA in high end residential construction. It is particular common in Santa Fe where I live now (for high end anyway) because the so-called "diamond plaster" look & feel is very popular. So, you st…

It is indeed how it's done in the UK. It's a bit of a cliché for British people to complain about American houses, but it's not that we don't have stud walls ourselves, it's just that we don't just go and paint directly on top of plasterboard. Both walls and ceilings are skimmed, with either plaster or shudder Artex. We also have dot and dab walls which are built from block, have a layer of plasterboard glued, leaving a ~6mm cavity, then skimmed with plaster.
