Laurence Llewelyn-Bowen and Whinnie Williams are in the West Yorkshire village of Haworth, to help a mother and son make over a room in each other's homes. Mum Sonya is helped by eldest son Nathaniel, while younger son Christian works with his girlfriend Charlotte, updating a pokey kitchen and a living room with office space. But as they find, updating historic buildings without losing their charm, as well as dealing with wonky walls and uneven surfaces, brings its own challenges.
