Good architects match modernism with livability. A couple months back I visited the Barbican Centre in London and it never ceases to amaze me how thoughtful is every little design item.
As such the vast majority of the Barbican's disparate cohort of brutalist concrete buildings in the UK were not built for humans, they were built for middling architects who were never going to have to suffer living in them. They need to be razed to the ground and thankfully many/most are going that way.
Stark, grey-brown, crumbling, water-stained monstrosities that just add to the feeling of misery in a country which is already stark, grey-brown, crumbling and water stained in so many other ways.
