The Barbican

The Barbican is such a striking example of an architectural utopia, built not just as housing, but as a statement about how people could live, work, and engage with culture in one integrated space.

Few others worth exploring...

Walden 7 (Spain): A labyrinthine, colorful complex by Ricardo Bofill with inner courtyards and skybridges, aiming for a more social urban life based on B.F. Skinner's Walden Two philosophy.

Arcosanti (USA): Paolo Soleri’s desert experiment in “arcology”, architecture + ecology—exploring sustainable living in a compact footprint.

Unité d'Habitation (France): Le Corbusier’s "vertical garden city" combining apartments, shops, and communal spaces into one concrete megastructure.

Habitat 67 (Canada): Modular housing units stacked like Lego, Moshe Safdie’s vision for dense yet humane urban living.

Auroville (India): Founded in the 1960s as an experimental township aiming for human unity beyond politics and religion.

I'm not sure how to feel about most of those these days. They are iconic and I'm glad that experimental ideas actually made it to completion, but ultimately they have failed at reimagining life for ordinary people.

In the cases of the buildings, over time their value has increased faster than an average dwelling in the vicinity, making them more exclusive and restricting access to those higher and higher up the socio-economic ladder - effectively turning them into gated community without the residents needing to feel the guilt of living behind physical gates.

The buildings are still there, and they have inhabitants, but the investment potential has long outlived any philosophy. I guess you could argue there are some secondary effects from their influence, but I wonder how the architects would feel today.
