I would love to know the mindset and thought process of Brutalist architects and admirers who see that and see beauty whilst the majority of the rest of the world sees a broken down leaking eye sore.

We are so far apart it is like trying to understand and alien.

I have seen a scant handful of Brutalist building that I consider fine works of craft but the gob smacking majority are pitiful piles of concrete and exposed trusses.

I don't think I've ever seen a Brutalist building that I consider good. Worse still, stupid architects get them heritage listed so we can't even replace them with actually useful buildings (i.e. https://en.wikipedia.org/wiki/Cameron_Offices,_Belconnen)
