Identify the location please! Essex or Surrey perhaps?

Barry, have you found your Grandfather on the 1939 register as that would tell us if he was in the same area and may give more details about his occupation?

   It is the Admiralty Research Laboratory, Teddington.

That's said with authority, SB - can you show why you think it's that? I'm not convinced it is the same place or that a chemist would be employed there. Willing to be proved wrong though!

This photo is from the Research Lab - might help to identify if it is the same place

The building in the OP's photo is from a later era than The Admiralty Research Lab as suggested with authority by ScouseBoy.

SB, Can you provide an image which shows similar architecture, preferably the same entrance, to that in the OP's photograph?

[rosie99]

I am not convinced about the Admiralty Research Lab.  The link I posted earlier has photos which indicate that any doorway may have an 'Anchor' over it.  Also the windows are not the same type.

Hi  Just coming in on this with my two pence worth

Does that look like a tower in the reflection of the window on the left side of the entrance?
also, is that a bridge like structure in the reflection of the window on the far left?

Frank.

Yes I was wondering about the reflections? 

I can't find any photos online, but the Sir Charles Morgan Building apparently built 1925, extended 1927/28 and completed 1933 housed the National Chemical Laboratory which joined the NPL in 1925. Looking at the location on the map in this document, it looks like a building of the right size and location - but as I say, can't find a photo ... so could be totally wrong.

I think I could well be a million miles away here, but, could the photograph have been taken looking the opposite way from the group photograph at the A.R.L Teddington on this link, Bridge like structure as well as same style of suits. 

Frank.
