Kevin's cabin is now habitable, but he has yet to add the vital furnishings to turn it into a comfortable home. And more pressingly, he has nothing to cook with. It's time for some fiendishly clever off grid solutions. With Kevin's cabin not connected to electric or gas, he examines a leftfield experiment in north Wales, where they're turning dog poo into methane. And as the cabin will be a place of rest, Kevin decides to make an armchair out of a 1950s tractor seat.
