In the last recession, 40% of architects lost their jobs. Are they prepared for this one? And how will the crunch affect our once-booming cityscapes? "I didn't lose any work in the first recession I experienced," says Zaha Hadid, "because I didn't have any work. I was drawing with freezing cold hands in rooms lit by candles. It seems almost unbelievable now. If I learned something, it was that anything can happen. We're doing well today, but this is partly because so many of our projects are in places like Dubai, which seem immune from recession (not necessarily.) But you never know." guardian
