Alan Titchmarsh and the garden makeover team head to Chippenham, Wiltshire to create a traditional formal garden for an inspirational couple. Richard Warren has been a serving Special Constable for 52 years, and dedicates his spare time to running marathons to raise money for charity, and caring for his wife Lynette, who has multiple sclerosis. The team shares tips on how to create a formal pond from scratch, screening solutions for unsightly spots in the garden, and reveals how to mark out a perfectly oval lawn.

Alan Titchmarsh and team set out to create the ultimate lush Thai garden in Leighton Buzzard for a paramedic's family and their four rescue pugs.
