Just caught the last few seconds of an advert for a show that's airing tonight (Sun 23rd Sept) on Channel 4 @ 8pm - Kevin McCloud's Man Made Home, it appears to be a show about Kevin McCloud's dream to build an eco cabin in the woods, either from stuff he makes himself by hand or rubish from others.
I'll definitely be watching this one!
Here's a description of the first coming episode:
"Kevin starts work on his hand made home by venturing into the bowels of London. With mains electricity and gas not an option for his bolt hole, Kevin hopes to make biodiesel for a lamp from the huge stinking 'fatbergs' that clog up the city's sewers.
For the cabin's structure, Kevin cuts down two ancient oaks, and starts putting together the wooden shell of the building.
He also experiments with a Wild West technique of splitting logs by gunpowder, and tries to make the whole cabin mobile because of planning regulations."
