In this edition, Alan heads to Banbury to surprise two young carers - 12-year-old Claudia and nine-year-old Leonie - who look after their mother Donna when her husband Lee is working. Donna lost about 70 per cent of her sight after a heart attack, which has left her with severe tunnel vision aggravated by low lighting conditions in their dark cramped house, while their lumpy featureless yard offers little respite. Alan and his team - architect Helen Sisley, builder Kunle Barker and gardener Katie Rushworth - transform the family's indoor and outdoor spaces into bright usable spaces, with astounding results.
