Kevin McCloud ( above) meets Harry and Briony Anscombe, who have decided to move from London to Cornwall with their three young children and begin building work on an ambitious house, inspired by American modernist properties. With a budget of just £ 400,000, Harry opts to project manage himself, paying local builders by the hour, but his lack of experience in construction proves to be problematic.
