You mention the private equity backed builder, but the designs come from the corrupted ivory tower which just invents more and more ridiculous designs (modernism, brutalism, for example) to try to stay fresh. Same in the art world. (Banksy, Warhol, others)
We have not made any progress, and perhaps we don’t need to, when it comes to architecture since World War I. There have been a few projects like La Sagrada Família, but those are exceptionally rare.
Suburban homes. What a disaster and embarrassment to the human race.
What do you think is weird about Banksy? Looks like older pre-modern art to me.
If you like neoclassicism and hate brutalism, then I would say you are very strange too. To me, brutalism hits the same things neoclassicism does but much more organically and better.
