JP (2017, e.2020):
These are two privately occupied houses, with steps leading up to the front doors. No.24 has recently [2020?] been sold. At one time they formed the boundary between Wandsworth and Battersea.
[PB: Add a map etc this boundary, and perhaps on the road between Tooting and Battersea that once ran along it.]
Notice, incidentally, Earl Spencer's encroachments (outlined in red) along the future Bolingbroke Grove. Also the "Ghost Road" crossing and re-crossing the parish boundary - it is not the future Trinity Road. It would have emerged more or less exactly half way between the future Wiseton and Althorp Roads [today's building numbers 22 and 23? [23 and 24?]].
Looking across the Common you might be able to see in perfect alignment the remaining parish boundary posts on the Avenue and on the corner behind the backs of the houses on Routh and Baskerville Roads.
