David Dimbleby tells the dramatic and heroic story of Britain's architecture - the extraordinary buildings which grew out of the experiences and beliefs of the British people and define the nation. From magnificent cathedrals to Glasgow tenements, from the medieval castle to the hi-tech corporate HQ and from the splendours of the most palatial stately home to the urban terraced house; from the invention of our industrial cities to the cosy postwar prefab - not forgetting railways, bridges, canals and lidos - this is the story of a thousand years of change in Britain's buildings. Travelling around the country, David Dimbleby explores how a particular period of architecture gave each region a unique character. From the cathedrals and manor houses of medieval East Anglia to the singular development of Scottish buildings; and from the dramatic mills and mansions of the Victorian north to the suburban dream houses and modernist visions of London, he takes us on a tour of the wonderful buildings, relates fascinating stories about their inhabitants and social history and asks: can architecture really make a difference to our quality of life?
