Mystery WWI camp - not Lark Hill

[Moonraker]

I'm just a little intrigued about which camp this postcard shows. On the back is the annotation "Dad Camp Lark Hill 1st War", but it's nothing like Lark Hill - nor is the card of any other camp in Wiltshire. The only similarity is the railway embankment in the photograph, which might misleadingly bring to mind the Lark Hill Camp Railway. But there was no large house (as shown on the skyline) near Lark Hill, nor were its huts white.

(My link is likely to become dead once the listing ends on Wednesday afternoon.)
