19c prefab buildings were made of tin [audio 7min @1:22]

Dylan Winter reports on the pre-fabricated, corrugated iron buildings that were thrown up to meet the demands of a rapidly urbanising society in the 19th century and which still survive to this day. Largely used to provide places of worship, they are sometimes referred to as 'tin tabernacles'. Dylan speaks with Ian Smith, author of Tin Tabernacles: Corrugated Iron Mission Halls, Churches & Chapels of Britain (Camrose).
