I rented a newish Bovis home and had reason to take the kick panel off the kitchen units, behind it I found all the kitchen fitter's rubbish from 6 years before, including the kicthen packaging, fag packets and a handy copy of The Star that enabled me to precisely date the find.
Amazingly common, one chap didn't bother with a skip and stuffed three tons of rubble under the floorboards.
