It's fascinating how boom and bust this is. You look at the City, or at King's Cross and there's just been a total transformation. Then you look at Nine Elms or Highbury and really very little has changed.

You've got Wembley - massively built up, loads of carparks gone and building in it's place. Then you've got the Millenium Dome, one big car park in 2007, one big car park in 2023.
