Kevin McCloud and Anna Keay present the nominees for buildings constructed in the 20th century. Anna takes in Castle Drogo - the last castle built in Britain, Jonathan Foyle loses himself in the art deco glamour of the former Birmingham Central Fire Station, and Marianne Suhr uncovers how a much-loved building in Newcastle has been rescued from the brink. Kevin and Anna then hear which building the judges have put through to the shortlist before the overall winner is revealed. Last in the series.
