[quote Radleygirl]@Bumpandus good luck, fingers crossed you get some progress today!
@Lurchermom Thanks, yes it is old not exactly sure how old but it’s a barn conversion. Not sure he’s a specialist in historic buildings but he was recommended locally as being experienced with conversions. It’s the back wall, there aren’t any windows in the back wall as they would look at another barn on the farm, so we can’t see if without accessing the farmers property. If that makes sense. The woodworm he said there was lots of holes, but they weren’t necessarily active but he would advise treating it. He didn’t say exactly where, I know I’ll just have to wait for his report.
He did prepare us before hand that as it was an old building there would be issues, I think I’m just getting nervous now as it’s practically the top of our budget so we don’t have much money left to play with.
Friendly suggestions are always welcome, especially when I get the report and panic sets in

Sorry, I missed this!
Good that he knows his way around a conversion, it would definitely give me more confidence. The concern with the bowed wall, Is think, is that when the roof was replaced when doing the conversion that it was too heavy for the walls and the foundations. It could be that the original wall was bowed, but then I would worry about an inherent flaw (ie that the original design was compromised and replacing the roof etc will only compound and repeat that). But if during the conversion they tied the walls in appropriately, provided support or added extra to the foundation's then it could be that the building is no longer compromised and just retains some extra "character" - after all you see old buildings with topsy turvy walls all the time. Though in conservation circles there is often a policy of "don't ask questions" if physics is questionable!
With woodworm I take treatment with a heavy dose of sceptisism. Unless there is significant and obvious signs of current activity I would just leave it be - it's been a barn, it will have had woodworm. Most woodworm companies will come around, ooh and ahh and tut and charge you a lot of money to spray chemicals all over your house for absolutely no reason. I'm not saying it's never needed, but unless you are seeing lots of piles of woodworm dirt I wouldn't be concerned personally. It more a case of checking the timbers for signs of flaws as a result of previous woodworm activity, but my guess is as a conversion that should already have happened and been replaced.
It sounds like a place full of history and charm, I hope the survey comes back quickly and without too many horror warnings!
