That's coming along nicely.
Thanks...a bit slow for my liking, but I’m basically limited to a bit of time at the weekend. Probably should have brought a load of stuff with me while I’m away for work, but my car is pretty much stuffed full of gear already

My initial plan was to have a whole wall collapsed, but I’m thinking now that (despite their ramshackle look) the walls will be still standing, but with a piece of roof caved in....all dependent upon future progress.
