Kevin McCloud visits a couple planning to build a home that looks like a work of art overlooking a valley in south Devon. Joe and Claire's new home will be a giant sculpture inspired by the local landscape, 70 metres long and featuring 34 enormous angled zinc shards jutting out in all directions.

And although Joe is wealthy, ambitious and fearless, his team quickly come up against problems and the budget virtually doubles the first walls go up. Is his dream home in danger of become a nightmare?
