Statement of significance:

Igloo House, dating from 1951, is of State aesthetic significance as an important early example of modern house design in Australia, which is innovative in its use of structural technology. It is significant for its association with its designer, leading Australian architect Harry Seidler, who had been a teenage refugee from Nazi oppression in the 1930s and who had trained as an architect in Canada before coming to Australia in 1948 to design a house for his immigrant parents. Igloo House is thus also a demonstration of the contribution of immigrant culture to Australia.

Physical description: Unusual twin-arched garages and light concrete body set on poles on the waterfront cliff. It was designed by Harry Seidler in 1951. A distinguishing characteristic is a double-arched garage roof offset against a concrete wall, with a backdrop looking towards Sydney Heads. The first Australian house to use flat-slab construction, with special concrete developed by a Sydney engineer, Peter Miller, that did away with heavy foundations. The house has been subject to several alterations since construction.

History

Historical notes: The site was purchased by George Laurence Williamson, a solicitor who emigrated from Britain in the late 1940s. In 1951 he commissioned the design from the innovative immigrant architect, Harry Seidler. The innovative engineering design, utilising concrete slabs on piers, was undertaken by Peter Owen Miller. The house was built in 1952-1953 by Williamson as owner-builder using various tradesmen. Outfitting of the house appeared to continue for some time after this. Williamson sold the house in 1970 and subsequent owners have modified it since then, though retaining the basic structures. (Weirick 2001)
