WW2 German soldiers stationed in Norway

Hey Everyone

I am currently trying to identify where my grandad was stationed when in Norway, he was part of the signal corps within the Löwengeschwader (lions squadron) in Norway. I have pictured of the place they stayed but nothing is written on any of them. Does anyone recognise the building? I know long shot.

Edit: I have found in my research he was part of the Luftflotte 5 Nord West group based in Trondheim. However I am still keen to locate the building if possible
