Kevin McCloud meets a couple who bought a ruin and moved to Italy in 1999, hoping to start work building their dream home in Tuscany. Since then they've spent all their time trying to get planning permission, but finally, after four years, they are about to start work. And it's an epic project: they have bought a derelict 1,000-year-old castle in the Tuscan hills. Now, the couple face their biggest battle of all: rebuilding this massive ruin into a comfortable and luxurious five-bedroom home.
