Thanks for the link, your right there's loads of info, to be honest mate it's not a get out but with regards to the photos, I've not taken many, my method was to get a good note pad, a tape measure and a digital vernier for measuring the timber thicknesses and polystyrene insulation, after that we just stripped out the rotten timbers and just took note of where each one was placed and where there were any aluminium panels bonded under the ply wall boards, these are for the bunk beds and table supports, the tools we used for stripping out the timbers were good sharp wood chisels of various sizes, an old pointing trowel cut down and the point removed, this was used to separate the ply from the polystyrene, wall paper scrapper to remove the polystyrene insulation from the aluminium outside skin and some old pointed sharp kitchen knives to dig out the rotten wood, the best bit of advice I can pass on is, take your time and work methodically.
