If you have a northlight building and need a loading dock, what do you do?
Something like this if you look at Merlin Archery's factory in Loughborough. This is a proper old-fashioned looking building, if the cars weren't there (and possibly the security grilles) you could well believe we were seeing a 1950s scene. Even the colour is right.
Have a look on Google Streetview - don't forget to turn around and you'll see the Great Central too.
