I'll do some research on it, google is useless as always, because for "sponsored projects" and "innovations to save the third world" they take them appart and build using the boards, that is useless info, because they do too much work for it to be effective. I was thinking something along Mr Hamish's lines... But plaster boards are excellent on their own, so no need for pallets, only a simple frame. Needs to be cheap as chips too. So my idea for now is to use the pallets top for inside and the 3 bottom boards for outside. Put maybe some wool if I can get or sawdust with lime and for outside cover it with some sheeting or such.... if I had wool, there would be no need to do anything with the inside. I think I should get a few pallets and build someting small to try out. Like Jared, maybe some tiny house. Yes, for furniture they must be better checked for quality, but there is some great quality out there. I've also found some hardwood red colored timber in some pallet. So there is something to do in this field.
