The foundations for the walls (as opposed to the frame and roof) are to be made of discarded car tyres. Over the last 6 months or so, the two-legs have been travelling here and there (under my supervision, obviously) around the county, collecting tyres from all sorts of places.
So far, we’ve got tyres local companies, Tanvic in Melton Mowbray, Geoff Fowkes in Ibstock, and Oakham Tyres, Oakham. We have around 200, but we’ll need around 450, with footing depths of around 80cm (4 tyres below ground level).
