Facadism - the preservation of historic facades, the creation of facsimiles in front of new buildings and the decorative exercises of postmodernism - is accused of destroying architectural innovation, of divorcing the interior and exterior of buildings and of reducing townscapes to theatre sets. Its defenders describe facadism as the way urban tradition and progress walk hand in hand. Facadism presents a critical analysis of a concept central to the way in which the city is being remodelled. Assessing architectural and townscape philosophies and their aesthetics, the principles of urban conservation, the process of heritage planning and the market forces of urban development, the book builds a complete picture of the causes and effects of facadism in the Twentieth Century.
