Kevin travels to Oxfordshire to meet the Randolphs, who built their first house 10 years ago and now, in their 70s, have decided to do it all again!

This project was a co-operative venture - 10 young families each put in 30 hours of construction work per week. Kevin travels to Brighton to meet a co-operative of ten young families, including ex-travellers and single parents, who are building both their own and each others homes. A housing association bought the land from the council for £58,000. Paul then worked with the association to put the co-operative together. All the members were people on the council's housing list.
