The team is in Aylesbury where Charlie and the brothers go against each other to win the right to make over the garden of Michelle and Alistair and their two daughters. Alistair, who is in the air force, and Michelle, a neonatal nurse, have been together for 16 years. They have a small back garden but they need it to work hard for them providing space for entertainment and relaxation and also where their daughters Tabitha and Jocelyn, who both have autism, can play.
