George heads for Northumberland, where he takes in one of the most modern Victorian houses in existence - the water-powered, cliff-top mansion Cragside. He also adds his name to the list of dukes, earls and viscounts who've made the astonishing Grade I-listed Cliveden Gardens their playground over the past 300 years, and investigates the unique home of a fellow architect at Snowshill Manor in the Cotswolds, a treasure trove of more than 22,000 curiosities collected from all around the world.
