Garden Rescue: Nailsea

David and Alice have their hands full with toddler twins Beatrix and Martha. They moved in a year and a half ago, but have not had the time or energy to devote to their new garden. Low maintenance is key for any busy family, and the couple would like advice on how best to maintain the mature hedging which surrounds the garden. The old deck is rotten and slippery and there's an unusual fence separating the garden from a garden room used by the previous owners as a separate annexe. They've got £5,500 for designers Charlie Dimmock and Chris Hull to bring both parts of the garden back together as a family garden in which the twins can play whilst David and Alice make the most of the evening sun at the back of the garden
