I feel like you may have missed some things in my post.
I already acknowledged the explanation of ground quality for *that specific city*, but are you saying that the majority of US cities have ground quality that make building high quality high rises imposssible/impractical?
Also, I then mentioned high quality low rises. Are you saying that the majority of US cities have such poor ground integrity that even building a high quality low rise is also impossible/impractical??
I feel like I already stipulated the point that you corrected me on...so I'm a bit confused.
High quality construction is expensive no matter where it is located. Builders can make more profit if they build cheap, low quality buildings that barely pass the local codes. That's not a ground integrity problem, so much as a question of what produces the best return on the invested dollar. Not all developers cut corners, but those who do are seldom held legally or financially accountable.
Planned obsolescence may also be a factor, along with the fact that building depreciation can be claimed as a loss for tax purposes.
Okay, but now we're circling back to the points I made earlier. If that's the case, then why is high quality, multi family home development so common in Canadian cities?
There are more than a half dozen highrises either recently built or currently being built around my 3 highrise complex. So obviously in some markets the building of this type of housing makes sense.
It can't be fundamentally impractical to build dense housing. I just refuse to believe that because it's not what I see literally all around me. As I said, I'm willing to believe that some regions have ground structure that make highrises I'll advised, but that can't be the majority of US cities, right?
So that comes back to demand.
This thread literally makes me feel crazy.
No... it does not come back to demand at all. Having lived 22 years in Calgary, Edmonton, and some cities in Ontario, I'm qualified to talk about the differences between Canadian and US construction. There are radical differences between what's needed to create a residential building. These radical differences translate into dollars. In Albuquerque the problem is shale, however other US cities have problems like earthquakes, hurricanes, and seasonal tornadoes. Admittedly every region has its own construction challenges, yet some of those challenges translate into an economy of scale that favors group living, and others do not.
You've surely noticed how deeply utility, water, and sewage lines need to be buried in areas where the ground freezes. I grew up watching 3-meter deep trenches be dug to supply water to houses, and if a water main broke it was a serious construction problem. The first time I saw residential construction in Phoenix, Arizona, I almost freaked out because I saw some guys laying a water pipe and covering it with only a few inches of dirt. "What happens in the winter?" I asked my mom. "Nothing," she said, "because it doesn't freeze here." I was deeply affected by the fact that there was a place where construction was so cheap and so easy that all you have to do is scratch a line in the soil to provide a major utility.
Back in Calgary, the farther away a building was from the water main, the longer the hole was necessary to run the pipe. Therefore, it was more economical to build houses that were closer to the roadway. Also, the cost of digging the hole was the most expensive part. Once the ground was open, it didn't cost much more to put in a bigger line. Doing the sewage, water supply, and electric cable for a 4-plex or 8-plex didn't cost much more than running the utilities to a single dwelling. This means that, in Calgary, the economy of scale favors multi-family construction when it comes to utilities. In a hotter climate where the trench doesn't have to be dug halfway to Hades through packed clay or even bedrock, there isn't as much of a savings to be had from multi-family dwellings due to utility installation.
Then there's temperature management. Although air conditioners exist in some of the lower-altitude Canadian cities, for the most part the emphasis is on heating a building instead of cooling it. The reverse is true in most of the low-altitude USA. It's a geographical latitude thing. (We have a lot of hot air here, even without turning on the news.) So whereas a designer in Canada tries to minimize heat dissipation by building upward and creating more cube-like buildings to conserve heat, a designer in a hotter climate does the opposite.
The hot-climate architect tries to reflect heat and maximize dissipation while maximizing cooling. Some of the design hacks are over a thousand years old. The farther south you go the more you will see Moorish style enclosed courtyards and compounds with multiple buildings. The goal is to make air move through constricted spaces and then expand, because as it expands it cools. Likewise, tile and stone floors, or even concrete, have a cooling effect so slab concrete scores another win. Throwing more electricity at the cooling problem, while briefly trendy, wasn't possible for most of human history and isn't a viable ecological choice long-term. What does this say for the economy of scale? It actually pushes designers in opposite directions especially if they're on a budget.
For heat conservation vertical buildings are the way to go, since the ratio of living space to exposed walls will be higher. You see a lot of this in the older town homes in New York, Boston, and some of the older, colder US cities. The math is even more favorable in a high-rise, because everyone benefits from the fact that hot air rises. People on higher floors benefit from the fact the people living below them and beside them heat their dwellings, because with less of a temperature differential between two sides of a given surface the heat lost to conduction is less. Speaking of walls, exterior walls tend to be expensive because they must be thicker and, in many cases, insulated with something besides air or cinder block. Accordingly, a building design that minimizes exterior walls will tend to be larger, taller, and approaching a cube. You see that a lot in office towers. The things that go along with a tall building (such as elevators) can be divided among a larger group of people. Moreover, the same things that insulate against heat also tend to muffle sound.
If the goal is to dissipate heat, especially in a humid climate, you flip a lot of the heat conservation problem upside down. A narrower building is preferred particularly if it's possible to open windows on opposite sides of a house to allow air to flow through. Whereas insulation in colder northern climates is chiefly to keep warmth in, farther south the purpose is to keep the heat out. Air, in many cases, or plain cinder block, is sufficient. Building codes often permit exterior walls to be as little as four inches thick. So the cost of an exterior wall, compared to an exterior wall built farther north, is much
higher lower (edited to fix).
My final point is that expensive buildings of any size tend to be in places that aren't prone to floods, hurricanes, earthquakes, or tornadoes. Why? Insurance. Most people can't afford to replace their buildings if they're destroyed by a natural disaster. The ubiquitous New York brownstone, for example, is considered very desirable and trendy, and priced to match, but it's not going to be swept away by a tornado the way it would in most of Kansas. In the flood-prone Ninth Ward of New Orleans, the building couldn't be insured. If the whole area is likely to be wiped out within the next five years, actuarial science suggests that it's best not to build there, or if some shelter is vitally necessary, to put in something that costs less to replace than it would cost to fortify and insure.
TL;DR version: the physical conditions throughout most of Canada favor construction that maximizes interior living space and head count relative to utility distance and relative to exterior surface area. The physical conditions throughout most of the USA favor construction that maximizes exterior surface area, and the cost of running utilities to a property doesn't meaningfully affect the price of the finished building enough to incentivize multi-family dwellings. This is true regardless of other factors, such as zoning.
