^ My photo is of the Pedregal Artz shopping mall in Mexico City, a building which is not remakable of itself. After all, to put a slanting face on a shoebox and stack a few of them together is quite a common design idea these days - I think there's a museum in Liverpool that's similar. One thing we can reasonably expect of a building, however, is that it stays up, or to use the industry's prefered phrase, "It maintains its structural integrity." Yesterday, part of the Predregal Artz mall failed that test! As no one was hurt in this completely unprovoked collapse, I think we are entitled to laugh with a free conscience:-
