Phil travels north of the border to Hopetoun House in the spectacular Scottish Lowlands. With VIP access to estate documents, Phil digs deep in the archives to uncover the extraordinary history of the house and the mind-boggling quantities of materials, skilled labour and money it took to create one of Scotland's grandest-ever designs. Having made their fortune from lead mining, the Hopetoun family spent big on their country pile, employing not one, but two celebrated Scottish architects. Accompanied by the current Lord Hopetoun, Phil inspects the lavish rooms, many of which are unchanged since Georgian times. He also meets the staff and tours the 6500-acre estate.
