Alan Titchmarsh and a team of architects, builders and gardeners transform the kitchen and garden of wheelchair-bound 15-year-old Josh, who has multiple disabilities. The kitchen is so tiny that Josh and his mum Benita cannot be in it together, and Josh's wheelchair won't fit through the back door so the garden is completely off-limits. Architects Ewald and George create a new layout in the house so Josh can move from the front door to the back garden with ease, and task builder Kunle turns the kitchen into a state-of-the-art conservatory so mother and son can cook together for the first time. In the garden, Alan creates a series of different rooms, each designed to appeal to different senses.
