I was wary of this at first - I've been jaded by utterly unattainable stuff from Grand Designs - but it's really ace. It's part Grand Designs, part Scrapheap Challenge, part River Cottage - this episode they've made glass from sand, converted a safe into a wood-burner (and had a sauna) and brewed up medieval concoctions for flooring and glue. Bunny glue!
"What is a shed for, if not trying out stuff?"
