Brian has been the one getting it down (I just help with getting it out and disposing of it) so he's had the worst of it, its a good job he isn't either claustrophobic or acrophobic. Its been impossible to do it continously (I think we'd have gone mad, or given up and left, plus Brian would have probably had a physical collapse of some kind) so it has probably only taken a couple of weeks of actually working on it.
We can now see exactly what we have and start to firm up our plans for the house. Since the thatch was a metre thick we have a lot of extra space now its gone.
