They do love a bit of railing in Kensington and Chelsea.  It’s unclear if they do it to prove how rich they are: “hey we have so much money that we can just waste 8ft of land in front of our house”, or if it’s there to keep the plebs out (and because they’re not allowed to build a moat).

Either way, the can stop us walking on their land – but they can’t stop Timothy hanging from their railings!
