Everyone should recognise this door by now...except the paparazzi waiting for Julia Roberts have now been replaced by gas works. See, told you this was the real Notting Hill. This is in fact the front door of the house that used to belong to Notting Hill's writer, Richard Curtis. He sold it for an unknown fee, yet being in Notting Hill, it's bound to be rather a lot. The proper inside of this house is nothing like the inside of Hugh Grant's place as shown in the film (apparently so, it's not as if I have been in there).
Unfortunately, the blue door is no more! It was auctioned off for the charity, and the house got a ordinary black door as a replacement.
