We also live in one of these houses. From previous research, 203-215 are all listed in the 1911 census, along with 203a-215a. These addresses are all individually listed as maisonettes, and were all obviously built as half houses. Ours - 201a however, does not appear on the census, but 201 does, and is listed as a "private house" The deeds to our property, from memory, only go back to the 50's, when a restrictive covenant was added at the time the deeds were split - 201's deeds go back further. Notably, 201 and 201a are split identically to the rest of the terrace, and physically seem to have always been seperate inside. Interestingly, 185-199 are listed in the census as "missing", suggesting these were possibly not yet finished or inhabited at the point of census. The terrace does not appear in the 1901 census. 217 is also listed as "private house", with a note after it - "1 house and 6 maisonettes building" This is the last entry on the census page, before Dunstans Road listings. Presumably the "maisonettes building" are the "missing" 185-199? 201 was owned by Charles Stanley White, a wood turner at a sports factory, his wife, and 2 year old son at the time of the 1911 census. 201/ 201a do seem to have a slightly larger gap between the centre windows than 199/ 199a. The window reflections in the photo do indeed look like Honor Oak mansions opposite. However, as mikeb points out, the family are standing to one side, with the photo obviously framed on that side as if that maisonette is their particular house, so the photo seems unlikely to be of 201, if it was a single house at the time. I'd have loved to upload my downloaded copies of the census pages, but sadly they are very clearly marked "crown copyright"... Thanks for the photo jimbo1964 - lovely to see this. It would be facinating if you find anything else.
