The Great Indoors. Laurie Taylor talks to cultural theorist Ben Highmore about his history of the family home in the 20th century and how houses display currents of class, identity and social transformation.

Also, the evolution of the bathroom. Architectural historian Barbara Penner looks at that most intimate space in the home, and considers how it became an international symbol of key modern values, such as cleanliness, order and progress.
