Agata and David live in Benfleet, Essex. They were initially attracted to their lovely new family home because of its massive garden. They thought it would be an ideal space for their autistic son Franik to enjoy being outside. However, they soon found that the size and awkward L-shape of the garden made it difficult to keep an eye on him. They are constantly concerned that Franik could hurt himself. The garden is now a source of stress for Agata and David instead of the haven of calm they hoped for. Now, with a new baby daughter, this family is more desperate than ever to transform this giant space into one that can be full of happiness and relaxation.
