Revisited - Kent: The Eco Arch (Revisited from S9 Ep4)

Kevin McCloud revisits an arch-shaped home made of clay tiles in the Weald of Kent, built by Richard Hawkes, who designed the property, and his wife Sophie. It was intended to be self-sufficient in energy and supply some to the national grid but serious problems occurred when the arch collapsed during construction, so the presenter returns to see if their innovative home has lived up to its promise.
