"Brutalist architecture" looks to me a lot like every other building here in Warsaw Pact countries.
It has a defined style, my absolute favourite is The Barbican Estate in London

When done without style it's horribly oppressive though but I don't think any less oppressive than the nasty steel and glass monoliths going up everywhere.
Also I love concrete, when done using high grade materials and polished it leaves a lovely finish approaching marble.
I'd quite like to use it as a material for furniture but for the weight problems.
It's telling though that so few people go there. To walk east from Barbican tube station, you can either go along Beech St (through the tunnel built for motor traffic under the Barbican) or over a footbridge and across the Barbican itself, which is quieter and has better air and doesn't involve waiting to cross any roads. The latter seems the obvious thing to do, but at rush hour the tunnel is busy with pedestrians, while the Barbican pedestrian level is almost empty.
