My office was right next to Barbican, I was going to rent a place there but I cheaped out. Still bitter about it.
The thing about Barbican is that it is an opinionated living complex. People who built it had an idea on how the urban living is supposed to be and sculptured that in concrete. Very few things are changeable there, that's why it also feels like a different time.
I enjoyed walking from my office to the tube and get amazed by this giant place everyday. Never seized to amaze me. I would occasionally go there and work at the public places, it was often empty enough to find corners or passages where I can just observer the life happening in distance.
