Yes, of course it's steel framed. I saw it go up too. But its bland expanse of featureless walls gives it the impression of being made of slabs of concrete - hence my comment. And I wouldn't call it post-modernism - I don't see enough architectural detail in there to qualify such a description. It just looks like a bland modern functional shopping unit of very little architectural worth. Oh and seeing as everyone's in 'picky-picky' mode, the name of the shop is 'Candy of Brixton', not 'Candys' or even 'Candy's'. So there!
