Work appeared to be taking place inside, and one person near by told me the phone lines are being reconnected.
They moved out in Feb 2012 with 17 job losses, so if they are returning it would be good news ! :)
Oddly enough the above pic is an old one, but looking at the snap I took earlier its exactly the same, even down to the ‘wet floor’ A frame still being in the exact same place 12mths later.
