Jonnie Irwin is house hunting in the Northumberland countryside with a couple wanting to escape busy urban life in Gateshead and who have a £500,000 budget to move three generations of the family into a new rural home that provides them with a peaceful quality of life. Along the way, Jonnie visits Bamburgh Castle, home to the ancient kings of Northumbria. While taking in some of its illustrious history, he also lends a helping hand with the year-round conservation tasks necessary to maintain one of the county's most iconic heritage buildings.
