Re: Could housing be cheaper and better if we stop building so many staircases?

The whole time I was reading this I couldn't stop thinking, "Sure, we can get more usable space if we ignore modern fire safety precautions." And also "pushing apartment capacity a few % points isn't really going to move the needle much on the housing crisis in many areas."

I don’t think the goal is to increase the apartment capacity of existing multi-stair buildings. Allowing single stair buildings facilitates multi family dwellings to be built on much smaller lots - even those that currently contain single family homes. Changing that regulation is the basis for why cities like Paris can’t maintain New York level postulation density without many buildings greater than 6 floors.

Good point: I'm in a suburban area where land is much easier to come by, so it's less of an issue. Although even then, 3-bedroom apartments are as rare as... Something very rare. (It's Christmas, metaphors fail me at the moment.)

Anyway, if they built floor plans like this then I would want to see some seriously bulked up building codes to deal with fires. Also it always strikes me as odd that sprinkler systems are used to help with the fire, but smoke is what mostly kills and I rarely hear of emergency ventilation systems tied to fire alarms. If anyone knowledgeable on that sort of thing could chime in, I always love to learn why my ideas are wrong/bad.

I live in a London apartment building with a single staircase, which is standard here. The difference in principle seems to relate to “what happens when there’s a fire?”. Here, we don’t need to escape if there’s a fire in the building[1], because regulations demand walls, floors and doors that can withstand many hours of fire, which provides more than enough time for the fire service to attend and extinguish the fire…

Is better fire isolation obviously cheaper than a second staircase? Depending on the footprint of the building, it actually sounds a lot more expensive.

A lot of regulations are designed to make new construction as expensive as possible and limit usable floor space as much as possible. No one should be surprised that fire safety laws are going to the extreme for safety at a large cost to floor space.

Municipalities in USA are adopting code for residential new construction to require sprinklers. Big cost that most people won't do anything to stop it because it is only for really big houses (for now). In fifteen years people will wonder why new housing is so expensive and every size house has sprinklers which the homeowner must hire someone to maintain. And pay for sprinkler inspection report prior to resale. On a…

My house had sprinklers and it was not a big deal. There was one special valve they said you should change every five years. But that’s the only maintenance anyone ever told me. No one had to check them before the sale.

Anecdotal, but I've never heard of an apartment building fire where people get trampled trying to escape. This in Europe where many if not most countries do not mandate a second escape route for midrise buildings. It's simply not a problem. You're supposed to shelter in your apartment anyway, which almost always is much safer than the hallway in case of a fire.

“ Overcrowding during emergency evacuation can cause crowd stampede and trampling that will lead to serious injuries or fatalities. ” https://www.sciencedirect.com/science/article/abs/pii/S09600...

Yes, but that is about large crowded events specifically, where the crowds can be tens to hundreds of times larger than the number of residents in a midrise, and remaining in a specifically constructed fire-and-smoke-resistant shelter (one’s home) is not an alternative.

As the article states, there are lots of Western countries (including mine) that do not require a second stairwell for midrise apartment buildings. It's not a theoretical question. In a properly compartmentalized apartment building, you should not exit your apartment unless it's the one that's on fire.

Well I am never convinced by an argument of "well others do it", that is never a valid justification IMO. The US has always done things different than the EU, and IMO that is a good thing. As to fire, that is but one of many other safety concerns, I personally will never live in a place that only has 1 escape vector, even if fire concerns were mitigated

Not perusing available evidence when making policy decisions like this is simply bad decisionmaking. “Doing things our way” just out of principle is just as silly as blindly aping others. It’s possible to (fallaciously) argue against anything by saying “but we’re special so doesn’t apply to us” and I’ve seen too many bad decisions made due to what is essentially a case of the NIH syndrome.

> Cars are designed to intentionally accelerate you to speeds that easily kill you And buildings in North America are often framed out of the same material that they burn in their fireplaces. Both present inherent dangers. Both have widespread safety regulations for this reason. Vehicle accidents are the 2nd leading cause of accidental death in the US and fires are 6th. And this is the result of many decades of both…

And I still find it surreal that people in world's richest country live in wooden houses. People still die in scary numbers there no matter the regulations. Cars can't be made safer anymore. 60Mphs frontal collisions have single digit percentage survivability chance because physics. Homes can be made much safer by building them differently.

> And I still find it surreal that people in world's richest country live in wooden houses.

A lot of those people live in seismically active areas. While modern masonry construction is certainly safer than traditional masonry, in general wood is far less dangerous than stone or brick in an earthquake.

The problem is that you can't track how many disasters were prevented by having two means of egress, so I cant imagine there are real statistics on that I hate the space argument because its a money argument, not a real quality of life issue - make the building 1 floor taller, or don't cram your residents just because you wanted to milk 4 apts instead of 3 on a floor.

> just because you wanted to milk 4 apts instead of 3 on a floor. You realize that this would mean the three residents would have to pay more for their unit, right? It isn’t just developers “milking” condo buyers or tenants. It has to do with efficiency.

Obviously thats the outcome, but thats not anyone's problem except the developer, and buyers know the price going into their purchase.

For example, if I can cram 14 windowless apartments into the same floor, is it really unfair that that 4 tenants would have to pay more than the 14?

And steel, or reinforced concrete are safer than both.

Wood tends to get a lot of criticism on the internet as a building material, but it has advantages as well. Cars can absolutely be made safer. They certainly haven’t stopped getting safer yet.

No amount of safety system will save you in a 60mph crash.

"Architects and developers", the people with a financial stake in recovering floor space, and sounds like they formed a lobby. Why its in slate is confusing, especially since the article definitely has a pro stance, with little research to back it up

> research why is questioning a regulation that already lacks evidence for its efficacy requires research? it's plenty of research to point at the other parts of the world that is not in flames despite higher urban density and only one egress per unit.
