Dreaming The Impossible: Unbuilt Britain

Discover plans for a glass transport loop around Victorian London and a 1950s glass city.

Using her skills to uncover long-forgotten and abandoned plans, architectural investigator Dr Olivia Horsfall Turner explores the fascinating and dramatic stories behind some of the grandest designs that were never built. In this episode she looks at two of the most radical civil engineering projects proposed in the last century and explores how international politics and vested interests both drove, and derailed, plans to better connect Britain to the continent.

A look at plans to radically reconstruct 17th-century London and 1940s Glasgow. Destruction, whether intentional or circumstantial, often creates a clean slate and demands a fresh outlook in which we come to think the unthinkable. This programme looks at bold, and in some cases shocking, plans to make revolutionary changes to Britain's biggest cities.
