I love Barbican. One often overlooked quality of Barbican is how much design work went into it: these corridors, galleries, balconies are all unique, many design elements are one-off, and there are more than 80 flat types https://www.barbicanliving.co.uk/plans/
This makes it much more organic, surprisingly, than most modern developments. It's not just the same thing copypasted over and over, Barbican has a very human, natural variety to it, despite the superficially harsh appearance.
Sometimes this variety can even backfire, because Barbican can feel like a maze. But that's a consequence of it not being the standard street grid. I wish we had more architecture like that.
