The Duncan House in Castlecrag, is historically significant as a fine example of the work of Walter Burley Griffin, an internationally significant architect. It is one of the original houses in the Castlecrag area, which were all built in the 1920s-1930s. The house is a diminutive yet perfectly proportioned example of Griffin’s work, using his patented knitlock concrete, ribbed and gracefully crenelated, yet grounded in the earth through the use of heavy rusticated protruding stone corner piers. The dwelling is listed on the NSW State Heritage Register.
Weir Phillips Architects were commissioned to redesign a sensitive addition to the diminutive dwelling, replacing an earlier 1980s extension. Weir Phillips Heritage and Planning provided advice throughout the design and pre-approval stages through to construction completion.
