The competition heads to Cornwall, where recycling queen Lynn Askew, retired hairdresser Don Hawkins, clean freak Georgie Murray and artist Vicki Bampfield-Hammond score one another's properties. They open their doors to a converted barn, a French-inspired home, a St Ives sanctuary and a place built from a boat, in the hope of winning the £1,000 prize. Narrated by Guy Porritt.
