About this programme

5/8. Kevin McCloud follows the progress of Brighton couple Daren Howarth and Adi Nortje, who want to build an earth-sheltered home from recycled materials, based on ideas pioneered in New Mexico in the 1970s. However, land prices and planning laws have forced the pair out of England and into Brittany. To keep costs down, Daren and Adi enlist the help of unskilled volunteers to work on the house, in exchange for teaching them the construction techniques.
