Whilst I have found out snippets of the past (which are covered on the main web site in more detail) I have just been informed by my friend Neil that the following site has a picture of Langton House as used in a Carry On Cabby film from 1963.

Great to see! If anyone ever spots any more old photos of Langton House PLEASE let me know!
