They've saved a flint mill in Stone, Staffordshire that's on the verge of falling down. Alan is a building surveyor, and shouldn't have a problem fixing the massive structural damage. But his passion for old buildings soon takes over and they end up ploughing everything they have into this build. George Clarke helps them every step of the way and uncovers its unique history and the link between this building and the world renowned pottery and ceramics of Josiah Wedgwood.
