Actually apartment buildings are mostly concrete. Strip away finishings like cabinets, drywall and flooring from a unit, and what's left is a concrete cell. Sometimes separating walls within a unit are wood based but that's rare too.

I think you and OP just have different definitions for "apartment building". I've lived in pretty large buildings (eg dozens of units and four floors high) that were largely made of wood in both the northeast of the US and California. They aren't high-rise buildings but I wouldn't argue they aren't apartment buildings, and they're far from uncommon.

Yeah I was thinking mainly of condo towers in cities, which I normally associate with apartment buildings. California has different rules due to high earthquake frequency. It's hard to generalize elsewhere.

Stick frame buildings are prone to dry rot, very susceptible to molding, and the addition of drywalls* make them objectively inferior for any building that's expected to last more than ~40-50 years. It used to be, 100 years ago, that the big cities like NYC, Chicago, Cincinnati, etc... were so dynamic that entire neighbourhoods were expected to be rebuilt every ~50 years or so. That's no longer the case. Over a lifes…

I may be biased, because I live in a city filled with houses over 100 years old, and we get incessant rain. They seem to hold up fine. Not sure how long they’ll last but there hasn’t been any push to replace them.

Have you ever done a mold spore count in your house ? There's a hypothesis that, due to living in stick frame houses, a large part of the American population might be suffering from a low dose chronic mold intoxication which shows up as a heightened state of inflammation.

I wouldn't be so sure.

As a German I always found North American houses and their drywall and wood constructions incredibly odd. It always felt flimsy to me. From my experience we just started using drywall for some interior walls on some newly built homes. But throughout my life I was used to very massive walls. I recently saw some house building videos and it is somehow fascinating how different the building materials and methodologies a…

I suspect the prevalence of "flimsy" wood and drywall constructions to be part of the reason why Americans dislike apartment living. They provide little sound insulation, are prone to water damage, have a shorter lifespan than the average person and once they catch fire they burn the entire thing down. Concrete or brick buildings are much nicer to live in, but expensive, so they are not very common among new construc…

Concrete or brick buildings are effectively illegal in much of the US because they aren’t safe. Large parts of the US are prone to earthquakes far more severe than any in Europe, a fact learned the hard way. It destroyed all of the prior masonry and brick buildings in the US so that type of construction is no longer allowed. Your choices are pretty much wood-frame or steel-frame construction.

That said, plenty of steel-framed apartments are effectively sound-proof. I’ve lived in them. You don’t need masonry, just wall mass.

Masonry can be engineered to US seismic standards but it is extremely uneconomical to do so. In my city, my house must be engineered to survive without structural damage an earthquake stronger than any in European recorded history. That’s not over-engineering, large parts of the US just have earthquakes that strong. It limits your material choices.

Similarly, US construction must also be engineered for extreme wind loading. Some of the buildings in my area are designed to withstand 300+ km/hr winds. Because that is a thing that can happen here.

Just about everything about US construction style can be explained by the necessity of engineering to survive extreme seismic and/or wind loading. Which it demonstrably does for the most part.

As a German I have to admit we are culturally odd with this. Our houses are way too over constructed and the dry-wall stigma here is just one aspect of it, wood construction stigma is another. It thus is no wonder that Americans have way more affordable housing. Those stigmas are also odd for most of our heritage-like old towns that are full of still-intact "Fachwerk"-Wooden-Constructions - which basically use the sa…

The materials used in US house construction are practically restricted by a requirement to survive extreme seismic and wind loading. In the US there are ghost towns where brick and masonry cities were completely obliterated by these hazards. As the US learned how to engineer buildings that mitigated these risks, these learnings were reflected in construction standards.

This led to the highly evolved wood-frame and steel-frame structures used in all construction in the US you see today. There are still a few old brick and masonry buildings from before these building codes, but most of the buildings from those eras collapsed in one disaster or another.

I stayed with a guy in France who had an old house with these picture rail things, and it was the first time I had come across something like that. I thought it was a very interesting solution for quickly rearranging artwork in your home if you love art but don't have enough wall space to display all your pieces so you might occasionally swap them.

But the noise.. this has been a huge factor in my quality of life, having lived in both buildings. That issue trumps any advantage drywall has, and I spent about 10 years working with it as well. I think the market forces have simply dominated our natural, economically inefficient, home-dwelling instincts. I think this article means well, but it is written from the perspective of a landlord basically.

Possibly the solution would be to have some kind of soundproofing backing material on the converse side of the drywall panels. Including this could be required by regulation which would be easier to enforce than some kind of abstract acoustic property. One of the interesting arguments that Brian Potter made is that you're usually better off trying to move the issue from construction to manufacturing.

This is basically similar to how leaded drywall is used to shield X-rays. Of course, there are additional costs associated with the hazards of lead.

Wood and drywall is how most houses in Sweden are built as well. Here's a timelapse of a Swedish house being built: https://www.youtube.com/watch?v=KbSm0Zw00Cs

The drywall wall is stronger, heavier thicker stuff and sometimes doubled up. We also often use steel work as the studs (particularly good professionals) as it’s stronger and faster than wood to put up. Then all the wiring is in conduits, and it’s acceptable to put water feeds on the outside of walls in the room for servicing. Then it comes to our bathrooms which are proper wet rooms and usually built to a very high standard to meet insurance needs.

I watch a lot of building videos from the US, it’s eyeopening watching for someone used to better construction methods.

The construction of UK inner walls is even better, it”s often plaster applied on plasterboard/drywall usually by skilled trades. Very strong.

> Because drywall is a dense and uniform mixture, hanging anything off the wall (from pictures to heavier items like shelves, TVs, or even cabinetry) is a trivial exercise, either a simple nail for a small frame, plaster anchors for medium loads, or toggle bolts for the real heavy hitters. yikes

Very yikes.

Also wrong:

> By eschewing the lath lattices, buildings now have way more room in wall cavities for improved insulation and conduits

The cavities are exactly the same size, plaster+lath, or drywall.

Most residential construction won't use conduit anywhere, and commercial construction would never bury a conduit inside a wall, regardless of wall covering.

These are weird things to get wrong.

In places like Boston there are many 100+ years old stick frame houses. They hold up just fine. Properly built wooden houses don't get any mold.
