Disappearing Bathroom and Reliant Robin

Architect George Clarke delves into the world of small builds, meeting people taking tiny, unpromising spaces and creating places to live, work and play. In the first episode of a new series, George meets a couple who are creating a disappearing bathroom and a man squeezing a camper into a Reliant Robin. He also discovers Chile's stunning architecture, and plans his hardest-ever build, an observatory.
