London House school of English was founded in 1965 and was relocated to another property a few years ago. The site is adjacent to Greenwich Court and is subject to a planning application.
London House was previously called Canterbury House, about which I failed to find any history on't interweb. However, there are artefacts to be found on site to suggest a sketchy history. In the early 60's there's evidence that the building was used as a convalescence home and during the Second World War it was used as an officers mess/billet for at least 151 regiment Royal Armoured Corps.

This is in much better condition than Greenwich Court and in my opinion the original features have been better maintained.
I found quite a few letters and bits of paper hiding about the place which date from the early 40's through to the 70's which really made it for me.
Thanks for looking.
