Lucy Worsley, chief curator of the Historic Royal Palaces, hosts this series about the ordinary rooms of an ordinary house and how they got that way. Each episode takes one room, the bedroom, the bathroom, the kitchen, the living room, and traces how it changed as ideas about privacy, class, cleanliness, and technology shifted underneath it. Worsley works from historical households and domestic records to show why a bedroom used to be a semi-public space, why bathing was once a rare and suspicious act, and why the kitchen's status in the home has moved up and down with servants, gas, and plumbing. The series treats the house itself as the evidence, reading social change out of furniture, plumbing, and floor plans rather than only out of documents. It stays close to Worsley's own research and access to historic sites, following the home room by room rather than telling one continuous story.
