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?
Conduit all the things and paint to match?
In the UK it used to be common for pipework to be exposed and painted. Electrical conduit is pretty common in "industrial" places like garages but the number of sockets people expect now would mean you'd barely have a flat wall anywhere.
The current preference is definitely for clean looking, square rooms. When pipes don't fit in the walls themselves, like soil pipes or around boilers, they are boxed in or hidden away in a cupboard.
Drywall is not too bad to deal with. And 99% of the wall surface doesn't need to be opened for a -long- time.
Drywall is manageable and cheap, I agree. But it's more painful than it should be for something that _will_ require maintenance.
And for telecom / low voltage, you have a lot of freedom of how you do it.
There are a lot of downsides though. You lose airsealing, if you don't have an airtight building envelope on the outside of the drywall. You lose fire resistance. You often lose aesthetics, although I've seen this done extremely tastefully. You lose childproofing, and run the risk of a kid electrocuting themselves or destroying your plumbing or dropping stuff in the wall. You impose constraints on what can go on the walls and where your furniture can go.
Given that drywall is pretty easy to cut and replace, most people figure it's just not worth the costs for something you do infrequently.
Personally I've been printing snap in access panels whenever I have to get into a wall these days - in white PETG they pretty much disappear into the wall for me.
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.
I've patched quite a bit of drywall, and I'm about mediocre at it. But it seems so silly and unnecessary to me.
Everything else in this world that requires maintenance comes with access panels and other means of easy access. In our living spaces, some of which should ideally last tens of years (mine is from the 1890s), we seal it all away.
Something less heavy, easier to fix without expertise, doesn't require applying some surface pattern to hide imperfections when used on a ceiling.
I guess something conceptually like a drop-ceiling (which has a "finished" look, but is very accessible for maintenance), except for walls. That's what we need.
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.
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.
But there really aren’t many walls you need to open in a house. There is probably 2-3 wet walls, so unless you need to retrofit some ducting why are you opening a wall? Code says there are no hidden wire junctions, so you’ve just got continuous runs of romex that are secured before they terminate… what do you open a wall for?
Most of the drywall repair is just physical damage to the drywall itself.
As I recall, wasn't PB basically a single vendor, too? Finding PB-to-anything-else adapters at Home Depot was like going on a treasure hunt. Sizing is different, so you really need something actually built for PB. And probably end up with sharkbites. If I were shopping for a house right now and found it had been plumbed with PB, I'd just turn around and walk away.

To be fair the article is about drywall and its history, not the history of all walls in general.
In my humble opinion, they are significantly better than pounding a nail into drywall. Of course, I also have an absurdly large collection of framed photographs and other art, all of varying sizes, and I love swapping frames around throughout my home. Having picture rails throughout my house means I don't have to keep pounding holes in the wall every time I replace that 20x20" photograph of my toddler shot in a square aspect ratio with a 16x20 shot on my 4x5, or whatever.
This is way better than arguing with partner about the proper height, making a destructive hole, then having to cover/patch when opinions or artwork change. My walls are not drywall, so that was a big factor, but the freedom to arrange/rearrange is a major benefit.
but, yeah, his videos are great. i've done more than my share of everything from sound abatement channels/glues/etc, hanging rock on vaulted ceilings, to level 5 finishes, but I still like to flip though his videos every now and then and pick up logistical / speed tips.
I'm not sure I would want a plaster skim in any case. I grew up in a house built in 1914 that had lath & plaster, and I've cursed the brittle plaster many times. We even had actual picture rails but my mom never liked to use them to actually hang pictures, amusingly enough.
[0] To be brutally honest, the texturing isn't for any particular reason aside from how well it hides minor imperfections. Having someone skim coat the walls and ceiling with a perfectly smooth finish is definitely a thing, but it's a good bit more labor intensive.
I'm not sure about the exact numbers, but I'm pretty certain this is a vast overestimate.
I've painted a more than average number of interior walls in the US (both personally and professionally) and except for a few that were wood, adobe, or lath and plaster, all the rest involved painting directly on drywall. Sometimes the base paint was applied with a thick nap roller to achieve a degree of texture, but I never textured one with something else before painting.
All I can guess is that there are large regional differences or cultural here, and each of us is having a very localized experience.
it is a bitch and a half for hanging anything (just like plaster on lath), plus it screws up wifi.
Pro tip for finding a stud, if you have access to the bare floor -- stick a drywalling knife / spatula under the bottom trim and poke. you can find the studs that way, and then measure off since 16" is pretty common. Measuring off the edge of an electrical box can work too, but you have to figure out what side of the stud the box is on...
> 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?
Wonder if in the future there will be incentives for proper disposal since you can extract hydrogen from it, other than that I agree with you.
For much the same reason they don't suffer from low heating bills, either.
The trick for this is to just find the stud. Same thing you'd have to do in drywall. For light stuff like photos, you can get away with putting a nail right into the lathe without having to find a stud. If you miss the lathe (you can tell) just move the nail up a half inch.
That is my piece of advice for anybody who is buying a house at least a hundred years old. Old lath is like iron, and you can do more damage than you expect if you just try to put a screw into it without pre-drilling.
The "cheap, uniform, and free of defects" story is partly a story about coal. The drywall industry scaled on the back of an abundant, nearly free waste stream from the energy sector. It's a classic example of industrial symbiosis — one industry's pollution abatement becomes another's feedstock.
And it cuts the other way now: as coal plants shut down across Europe and North America, synthetic gypsum supply is shrinking. The drywall industry is facing a real raw material squeeze, with manufacturers having to shift back toward mined gypsum or find alternative sources. There's ongoing work on using phosphogypsum (from fertilizer production) but that comes with its own radioactivity concerns.
For someone in your position this is particularly relevant — the "wonder" of drywall is entangled with the fossil fuel economy in a way that makes earth-based construction methods look increasingly attractive as that supply chain unwinds.
The gypsum used in New Zealand is mined locally.
2) Why emphasize asbestos when talking about plaster? My understanding is you likely have more to worry about if you have a house from say the 40s-70s, which almost universally have some sort of drywall product.
yikes
I recently saw some house building videos and it is somehow fascinating how different the building materials and methodologies are. North America obviously made it work, but still very odd to me.
I don't think of the walls as especially flimsy, though. Built correctly, they are totally fine. Yes you can punch a hole in one if you are sufficiently motivated (and you better miss the stud...), but the only times I've ever punched any hole in drywall it was because the door stop was removed for whatever reason and a dumb teenager threw the door open with no regard for propriety. At least drywall is trivial to fix.
Concrete or brick buildings are much nicer to live in, but expensive, so they are not very common among new constructions.
I personally like houses that use Insulated Concrete Forms for the exterior walls.
