Dan Cruickshank and Charlie Luxton uncover the incredible hidden stories behind historic buildings as they are dismantled brick by brick, and meticulously resurrected in new locations.Every year thousands of ordinary buildings are demolished, smashed down to make way for the new, but some are so special they are snatched from the bulldozers and carefully dismantled. When a new home can be found for them, they are lovingly and painstakingly rebuilt. These are not grand edifices, but everyday buildings that give an extraordinary insight into the lives of the people who lived and worked in them. Deep within their fabric are preserved astonishing stories about how we lived and worked.Architectural designer Charlie Luxton explores how these vast and hugely complex jigsaw puzzles are pieced back together, trying his hand at the array of ancient crafts required. Meanwhile, architectural historian Dan Cruickshank investigates the building's history, proving that even seemingly humble buildings have incredible stories to tell.This episode follows the construction of a fully working coal-fired Edwardian fish and chip shop at Beamish Museum. Charlie helps with the refurbishment of one of the world's oldest surviving frying ranges, and gets a horse-drawn fish and chip cart back on the road. Meanwhile, Dan discovers the surprising origins of our national dish and explores its rise from squalid back-street outlets to grand fish and chip palaces.
