 Many warehouses and industrial buildings in the central city area were facaded in the 1980s, some left propped up for years after the building boom bust in the early 1990s.New heritage controls introduced in NSW allow the listing of interiors, and many now are, and the City of Sydney heritage guidelines assume the retention of the whole of buildings that are heritage listed, and so there have been very few examples of facadism since the mid 1990s.In the rapidly growing city of Melbourne, facadism has become very common.
