This tiny shelter has been hidden for most of the year by Russian vine which spreads from the adjacent garden. I use it to dump stuff that I accumulate in the winter and then forget about it as it's invisible. Anyway, the local foxes have been using it as a landing area when they jump the fence and the other night I heard a crash - the thing had collapsed, probably due to a very large fox that we've seen around a few times. I want to demolish it completely and empty out the accumulated rubbish; it has a corrugated tin roof but the walls look suspicious to me so I haven't touched it yet. Is there any layman's way to test for asbestos? (My neighbour reckons that his identical one was a wartime shelter - possible, as the house was occupied from 1934.)
