No I can't work it out, but I think I can ask someone who might know :-)

It's difficult to line the houses up with cadastral parcels which would be a start. Also there's a gap between the houses halfway along. Some are flats, possibly even Victorian style maisonettes with different house numbers (ones beyond 264), but UPRNs don't help as they seem to have been allocated within the postcode not based on street numbers.
