Book excerpt: We spend our lives moving through passages, hallways, corridors, and gangways, yet these channeling spaces do not feature in architectural histories, monographs, or guidebooks. They are overlooked, undervalued, and unregarded, seen as unlovely parts of a building’s infrastructure rather than architecture. This book is the first definitive history of the corridor, from its origins in country houses and utopian communities in the seventeenth and eighteenth centuries, through reformist Victorian prisons, hospitals, and asylums, to the “corridors of power,” bureaucratic labyrinths, and housing estates of the twentieth century. Taking in a wide range of sources, from architectural history to fiction, film, and TV, Corridors explores how the corridor went from a utopian ideal to a place of unease: the archetypal stuff of nightmares.
