1941 Fighter Command Sector Ops Rooms?

Apologies for reviving this topic however I have something to contribute to the original question on 1941 Ops Rooms.

Thank you everyone for the fantastic information so far. I was previously (but no longer) involved with the restoration project at Barnton Quarry and before I read this topic (Admittedly a few years ago) I had no idea that the Sector Operations Centre at Barnton was a standard building.

Stornoway
This was an accidental find on my part so cant contribute more than the basics.
At Plasterfield, between Stornoway (town) and RAF Stornoway, we have what appears to be a now demolished 1941 style SOC with Internal Offices.

When viewing maps online I spotted a building of interest
This is from a sheet dated 1965:
maps.nls.uk/view/130125912

I followed that up by checking ncap website and found the building was present in a 1975 photograph.

I have uploaded a zoomed in image showing the roof of the building and personally think it matches the features of the roof seen on other SOC's.
 

If Tiree was built for the proposed Oban sector it would make logical sense this was built for the proposed Stornoway Sector which appears in some sector maps dated arround1941.

Many Thanks,
David
