The programme that follows British families buying and renovating chateaux in France returns for a new series. From crumbling ceilings to time-worn turrets, what does it take to transform these beautiful buildings? Donna and Paul have sold up at Château de Saugé and they're embarking on a huge new restoration project. They've bought a dilapidated five-storey Normandy water mill that needs a total overhaul, but is it more than they can handle? Meanwhile, at Château de Cézérac, Jon and Carmen are creating their dream bathroom. Access for their bespoke £12,000 bathtub is via a precarious ladder, a task made even more challenging by Jon's fear of heights. And at the picturesque Château de Bourneau, Erin and JB are beginning work on transforming their turret room into Erin's dream art studio.
