<P> Construction began in April 1975 on the shore of Lake Burley Griffin , in the Parliamentary Triangle . The site is just to the east of the axis running between Capital Hill and the Australian War Memorial . The High Court building houses three courtrooms , Justices ' chambers , and the Court 's main registry , library , and corporate services facilities . It is an unusual and distinctive structure , built in the brutalist style , and features an immense public atrium with a 24 - metre - high roof . The neighbouring National Gallery was also designed by the firm of Edwards Madigan Torzillo and Briggs . There are similarities between the two buildings in material and style but significant differences in architectural form and spatial concept . The building was completed in 1980 and the majority of the court 's sittings have been held in Canberra since then . </P>
