In Devon, George visits one of the National Trust's quirkiest buildings, a bear hut on the 6400-acre Killerton estate. The main house was given away because of the socialist ideals of the aristocratic family who lived there. George unearths secrets and scandal at Baddesley Clinton Hall, a fortified Tudor manor house in Warwickshire where in the past the architecture has meant the difference between life and death, then heads home to the north-east for a walk through Gibside Estate, a landscape park with royal connections and crowned with jaw-dropping architecture.

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.

George visits the majestic 1,000-year-old Dunster Castle in Somerset, once home to a clan who spent six centuries renovating it from fortress to family home. He discovers it's not size that matters at the country's finest surviving 17th-century water gardens, Westbury Court in Gloucestershire, and goes back to his roots in Tyne and Wear at Washington Old Hall, the ancestral home to the first president of the USA. George then trumps it all with a walk around the glorious Croome Park in Worcestershire, the 32-year labour-of-love of 'England's Greatest Gardener', 18th-century landscape architect Lancelot 'Capability' Brown.

George's journey begins in Dorset at the UK's most exquisite example of Italianate architecture - the magnificent 17th-century Kingston Lacy. He uncovers a tale of shame and scandal on the south coast, and the beautiful Cotswold landmark - Hidcote Manor Gardens - in full bloom takes his breath away. George also mines the history of the country's last cave dwellers at one of Britain's best-kept secrets, the Rock Houses at Kinver Edge, and finally, with his husky Loki, takes a walk at spectacular Studland Bay, part of the Jurassic Coast World Heritage Site.
