I had heard that office buildings were unsuitable for converting to apartments. But it looks like they're completely gutting the interiors.
Some office buildings will be more amenable to conversion than others, so part of this would likely be selecting buildings for conversion where the conversion is both straightforward and will produce nice apartments. You want buildings that have many floors but relatively small area per floor.
Like....
that extra space is a closet in my specific case.
Services is the other big one. Many more rooms needing hot and cold water and wastewater connections, more AC outlets and customisation, etc. Even if you have the space to do so (as office floor to floor heights are typically higher than residential). Plus remodelling facades to give more residential style windows etc.
And does your basement have enough space for the cars residents will demand?
Its an expensive business to add this all in and sometimes may be cheaper to just knock it down and start afresh.
Residential buildings tend to be a donut hole shape or an H to keep distances to windows about 20m. Office buildings are usually big, deep squares or rectangles.
Another thing is that offices can have worse sound insulation.
Or even as offices.

That sounds like quite a significant inconvenience. Didn't it put people off, in a "holy shit I'm not staying here for another second" kind of a way?
Nearly all instances go unrecorded, so precise frequency of distribution in England is impossible to determine. But they have spread across the globe to all countries and all continents except Antarctica, so chances are nearly certain you've got them in your home, even in England.[1] They're a little startling, but harmless to humans, and help keep your spider population in check. Even though I have probably only seen 5 of them in the last 20 years in places I have lived spanning the Eastern Seaboard of the US, I have no delusions about they being there regardless of spotting them. Unless they're disoriented and dying, like most "bugs," these things are supremely sneaky.

Gutting the interiors entirely is necessary, maybe they even need to gut major areas of the building to support more utilities as well. It’s probably not cheap so affordable housing may not be in the equation afterwards because of the renovation costs.
Before conversion? The two biggest obstacles are:
* Commercial mortgages make it nearly impossible to change a property in this manner, so you're usually limited to buildings owned free and clear.
* In most cities, zoning/planning would push back on this; I suspect the most interesting part of the Texas story is how they routed around that.
that's a contractual issue, rather than an engineering issue. This can be fixed with a stroke of the pen.
If I'm a bank holding a commercial mortgage, it's very finely honed to minimize my risk; as part of that, I contractually limit what can be done with the building.
Why would I, as a lending institution, throw that security away for something much riskier? If the emptying out of commercial buildings that we saw during the pandemic accelerated, that might have provided the incentive. But it seems like that trend line isn't going to continue in force.
I think converting high density commercial properties to residential is a great idea in a lot of cities. But ultimately it's going to be done almost exclusively in buildings that are mortgage free.
Not at all. Your commercial mortgage lender will always help you increase the productivity of your asset. Phone call. Excel docs. Talk terms. Lawyers. Done.
If you don't know this, nobody loaned you $#,#00M and you'll never need this advice
Where bureaucrats actually get to just make the decisions at a high level, rather than everything being second guessed by NIMBYs it's just really obvious what you have versus what you need. If you know your city has an inventory of empty mid-size office buildings sat on the market for months, yet apartments within walking distance of the city centre go for crazy money, it's a no brainer to authorise conversions. Whereas if the last office building was snapped up an hour after going on the market, while residential sales are crawling, a conversion from office to residential is nonsense, tell them to go away.
What really doesn't work is the partial conversion of offices on industrial/commercial parks out of town. It seems to lead to completely incongruous buildings, dumped essentially in the middle of parking lots, without basic amenities such as verges and pavements. Those buildings tend to be flimsy, and it's hard to see the environmental argument for keeping them. I would rather see those sites razed and rebuilt as better quality housing.
1) Office building and space is in demand but the market rate is much lower than the residential rate.
2) The owner of the office building will 'pretend' there is no interest in the property (sometimes for more than a year), so they can plead to the planners that they want to convert th building to residential.
The planners authorise the conversion and the owners make a tonne of dough.
There is no free market in real estate.
2016 Main was converted from a hi-rise motel into condos years ago, they are pretty nice but there is always the feeling that it's not a complete domestic environment.
At least the plumbing was there.
There's a couple more of these nearby that were left over from the oil crash of the 1980's, which were eventually abandoned after years of reduced energy travel. Looks like one of them has been gutted recently and might be under conversion now.
If you need intermediate pumping stations or holding tanks due to the height of the building, those could be inside adjacent to the outside pipes.
I wonder what causes these buildings to have such restrictions on plumbing. Maybe it's like elevator shafts where they eventually take up a lot of space if the building is very tall.
Conversely, adding more toilets, for example, may also pose a challenge. My dad helped design the plumbing system for a rebuild of a football stadium. One of the final tests was to have a bunch of volunteers go to every sink, toilet and urinal in the building and turn them on / flush them simultaneously to ensure that water pressure stayed high and the drain pipes didn't back up.
Adding more toilets in a building not meant for them can be a big deal right after lunch / around "busy" times... Some may not be able to flush or overflow if the pipes can't handle the extra activity.
Who instituted the limit? Was it in the lease terms, city ordinances, or something else?
This means you couldn't chip up the concrete slab to place new pipes, the way we could in e.g. a strip mall. This is an understandable limitation, because the integrity of slabs is important for tall buildings.
However, this wouldn't be a limitation in a residential remodel. They aren't going to mess with the slab or the pipes in it. They're just going to lay everything over the top of the slab. If the new toilet is 40' from the utility shaft, that is 3" for the pipe plus 5" for the fall. Add an inch for the floor itself. Average residential ceilings are much lower than average office building ceilings, so there is definitely at least 9" to spare.
Retrofitting all that additional plumbing is expensive.
Toilets are obviously a different story. But as long as no one is shitting in their kitchen or bathroom sink the water flow post-usage can in theory be managed.
I don't think it's a timing issue. The issue is that the fresh and wastewater plumbing simply doesn't exist in the places you'd expect in housing, so there can be a significant cost to adding it, beginning with just figuring out where you can run it through the existing spaces.
A holding tank and whatever pipes then are used to empty it are still plumbing, and even more complex than regular plumbing, unless you are suggesting that people would haul their own waste out periodically.
Also recall that wastewater pipes need to be at least slightly angled so that they drain properly using gravity, further constraining their potential paths. This can be quite difficult to design even when remodeling a regular house.
You can add drainage the same way, you just don’t need pumps for the drain stacks.
The residential tower is built with concrete layers separating every floor (not always every flat within the same floor unfortunately). An office building has no separation between floor, only a thin sheet of metal.
I would never live in a converted (purpose built) office building office, except perhaps if it is to live on the top floor.
By the way, the thin steel deck you saw gets concrete poured on it too once installed.
