Pony Lane and Stable Court Lane. Neither lane is mentioned on the library website and both lanes have houses dating from 1980s and 1990s.
I didn’t walk these lanes as they were clearly marked private. Stable Court Lane curves around until it almost meets up with Pony Lane. My best guess for the names of the streets is that there were stables here. Searched Papers Past and I found Spreydon Stables which were also called G W Watkins Stables. Mr Watkins dealt with racehorses and when there was a big Waimak flood in 1926 Mr Watkins stabled horses on behalf of people affected by the flooding. Mr Watkins lived on Edinburgh Street but I couldn’t find an obituary for him and I would have expected there to have been one.
I could be totally wrong but this is a possible reason for the naming of these two lanes.
