 Designers and foundries in the UK and France went on to produced all kinds of prefabricated cast iron structures and items for shipping to their colonies, from decorative elements to structural components to entire buildings.During the Victorian gold rush in Australia in the 1850s hundreds of various types of prefabricated structures were shipped out from England, in timber, cast or wrought iron, or a combination, often with corrugated iron for the walls and roof.They included houses, stores, three complete churches, and a theatre; the most elaborate surviving structure is the completely cast iron Corio Villa, in Geelong.
