Nick Knowles recruits extra help to renovate a whole house, making it a home with the latest designs. The team transforms the life of a family who have spent years living in a building site. Liz and her son James live in Chessington in Surrey, in a house that has been totally trashed by builders. Liz needed to get work done to help James with his special needs, so in July 2008 she spent 60,000 pounds on an extension. Six months later her builders scarpered, leaving her house in chaos and Liz in debt. The house was left unfinished and unsafe, leaving Liz feeling desperate and James vulnerable. Liz's sister Sue wrote to the DIY SOS team asking for help and, with an army of local traders, family and friends, Liz and James' building site of a house was turned into a home.
