Corrugated iron or ‘tin’ buildings are disappearing, literally dissolving, back into the land. All too often ignored, these often modest structures are expressive, vernacular edgeland architecture. Built using materials to hand and often re-purposing what’s found lying about, these allotment sheds, light industrial buildings, barns and outbuildings, demonstrate a bewildering array of pragmatic styles. The structures reflect the individual character of the builder; the properties of the building materials available; and the building’s evolving function and history. Tin buildings are a practical expression of creativity and engineering in harmony, and represent a practical response to a local need or circumstance.
