It's unlikely to be popular in the UK again any time soon, it reeks of depressing grey misery and inhuman, unfriendly architecture. It also reeks of crap 1960s city centres.

I hope this 'revival' is strangled in infancy.

I also disagree that it is function in form - brutalist buildings often fail to perform their function well, usually due to ignoring human factors like requiring light and air, or encouraging criminality and vandalism by having dark, semi-accessible corners.

I look at brutalist structures like the Heyward Gallery and despair that anyone could have thought inflicting that on the world was doing it good, when looking across the river at what else London has to offer.
