Other street name oddities: I grew up on a street that had different names on each side. In practice no one used either name, just the name of the larger road we were next to (our street was very short, just 12 houses in total). And a few streets from where I now live, a new house was built on a vacant corner site a couple of years ago. To one side is 1, #Street name. To the other side is the side street. So it's now 0, #Street name. But there's another vacant plot between it and number 1.... There's some weird street numbering on the other side of that street too, because all the streets in this area were laid out with houses on one side only and long gardens running down to the next street. It might have been built like this because it's on a steepish hill. Recently, houses have been built on what used to be the ends of those gardens, and some of the new houses have taken the number of the house whose garden they're in while some have tried to continue the sequence of the road they're actually part of. I don't know quite how it was allowed, but at least all the new houses (and the old ones, I think) are clearly marked with numbers.
