All the houses on our road have names, no numbers at all. If you look at the original 1936 building plans for our house, one of the 8 original houses on the road, the plots were named on the plans, and those are the names allocated to the houses.
This hasn't, however, prevented the Post Office arbitrarily assigning numbers ten years ago, which plays havoc with shops' address databases; there is one commercial database in use which only has numbers, despite nobody on our road using them. This results in our house being #16, despite being the 4th house built !
