Here’s a streetview: https://goo.gl/maps/bmFBmYywHAF2 walk around a bit and you see many such buildings. Only where bombs destroyed the older houses in WW2 will you find anything build after 1920.
The reasons aren’t necessarily a loss in taste: the older buildings have far higher ceilings, which may be due to them often being filled with far more people than is usual today. Alternatively (or because of that) heating costs did not factor into such decisions.
As to skyscrapers and larger buildings such as museums or hospitals, it’s important to remember that glass & steel & concrete is rather new technology. It’s far cheaper than brick, and simply a compromise between costs and appearances that was not commonly available back then. It’s also somewhat inconsistent but undeniable that we appreciate the decorative elements on the exterior, or the stucco inside, yet it feels somewhat tacky to make them today: McMansions are what happens when you think you can plunder all that’s beautiful from previous eras.
I don't know what happened to the buildings which housed the lower half. I know Berlin in 1900 was famous for having lots of awful newly-built tenement buildings, much lower standards than NYC or London at the same period. Maybe these were much less likely to be restored?
But I agree that selection isn't the whole story. Technology is some of it: heating was never cheap, but lighting was even more expensive, which is why old factories have huge windows. I think formality was another part, having a big formal room for guests was important for respectability, whereas today most housing is designed much more around its daily use... so things get subdivided to have more separate bedrooms.
The average architect lives in a building over a hundred years old.
The most desired buildings in the Netherlands are equally over a hundred years old, with people basically preferring faux copies (because buildings that inaccessible to the disabled are now illegal to build) to more modern architecture.
I’m aware there’re a lot of old buildings in most developed countries but there are more new ones. While there may be some bias towards keeping nice old buildings it’s not enough to explain the difference in quality. Old buildings straight up look better, they were designed by better architects.
Some ideas are just bad, not merely out of fashion, and history recognizes them as such.
They will continue designing in a style that wins awards and professional recognition, while the public are stuck with them for decades.
I mean, sure, the designer of the Stata Center [1] at MIT might have been aiming to impress other architects and win awards. That's why we've heard of it. The designer of Knox Road Multistorey Car Park in Cardiff wasn't aiming for architecture awards - which is why you've never heard of the place.

(I am pretty sure that every architectal project over a certain number of million dollars is guaranteed to win one or more awards)
I don't think it's selection bias. It's the same in software. User hostile faddish resigned are common, backed by some BS narrative. But other than the few times it had destoryed shareholder value (Snapchat) it doesn't really matter because the entire site/app will be redesigned in a couple of years. But a terrible concrete monstrosity can be around for decades and decades.
We used a semi-fancy architect to design our house, and while I'm glad we did we had to push's a lot to design in things like closets, much less other "habitability" features. Many award-winning buildings aren't actually as functional as the awards would imply (just think of the open office trend, which photographs well but is hardly good for productivity!). Ironically that same architect designed...a car park, which is actually quite nice.
(I object to MIT's relatively recent decision to start using names of donors for buildings rather than simply the building number -- building 32 is the stata building).
I can find pictures of the outside of the Cardiff car park, but I can't find anybody showing off the inside. What's so nice about parking in it?
The fundamental bottom line is that hardly anyone likes grey, and - in real life rather than black-and-white photos - no amount of interesting texture makes up for that.
