9 - 5: Brittany: The Brittany Groundhouse

Daren Howarth and partner Adi Nortje live in Brighton, and are champions of sustainable living. They want to build an earth-sheltered home from recycled materials, based on ideas pioneered in the 1970s in New Mexico. But land prices and planning laws have forced them out of England, across the Channel to Brittany, in France.
