I have been trying to find out a bit more about the entrance lodge to Coney Hall, on Croydon Rd for you K8T.
The family of Frederick Pelham TREVOR was living at "Coney Hall" according to various family notices in the papers, and they appear on the 1911 census with 3 servants. Although he writes the postal address as "Coney Hall, West Wickham, Kent", the enumerator has called it "Coney Hill Farm, West Wickham, Kent".
https://www.familysearch.org/ark:/61903/1:1:XWD4-XZYThe next house in the census is "Coney Hill Lodge, Hayes, Kent" occupied by Edwin TIDBURY (chauffeur) and his family. Is this the entrance lodge - possibly.
https://www.familysearch.org/ark:/61903/1:1:XWD4-X8QNext is "The Stables, Warren Wood, Hayes" then "Warren Wood, Hayes, Kent - occupied by Frederick TREVOR's step father John SMAIL and his family and servants. Then, "The Lodge, Warren Wood".
https://www.familysearch.org/ark:/61903/1:1:XWD4-X86The house previous to "Coney Hill Farm" is "Coney Hall Cottage, West Wickham, Kent" (occupied by John WOOD, farm labourer, and family)
https://www.familysearch.org/ark:/61903/1:1:XWD4-XZPand prior to that is the "Hartfield House stables" then "Hartfield House".
So looking at the 1909 map in reply #1
https://maps.nls.uk/view/103676678you can more of less follow the enumerator's route on the census in 1911. I think then that Frederick TREVOR was probably living at Coney Hall Farm, but the Lodge where Edwin TIDBURY was is most likely the one still standing on Croydon Rd. (I could well be wrong!) But, where is the house that became the Shaftesbury Society Home? If it was empty it should still be noted I would think?
In 1901 the enumerator's route is similar. The houses in order are:
"The Priory" - John Craigie ROBERTSON and family
"Coney Hall Cottage" - George FRY and family
"Coney Hall Cottage" - John WOOD and family
"Coney Hall Farm" - William STOKES and family
"Coney Hall Stables" - Albert and Ethel THOMAS
"Coney Hall" - 5 servants (Most likely the building that became the Shaftesbury Society Home?)
"Warren House Lodge" - William ENRIGHT and family
"Warren House" - 8 servants
I'm not sure that helps or makes things more confusing!
