Ron - Not sure exactly how far the houses went towards Church Road at that time- the above photo was about 1905, there would have been a row of shops (as in recent times) there, and maybe some other houses. Local street directories would confirm this.
Below is one which shows Elms Vale School in Markland Road , (pre 1936) - as the first house past the school, (No.46 Markland Road) on the school side, was not built until 1936, Bob's parents were the first owners, the house was in the family until about 5 years ago. Bob was born there. Houses on the other side of the school (right of picture) were much older and in a terrace.
Elms Vale Road (centre of picture), semi detached houses were then being developed, appear on photo on one side of road only.
Dover Grammar School (fairly new building then), can seen at top of photo.
