original Griffin plan, and the objective was to provide a 'horticultural suburb' and a 'society suburb'. In Griffin's 1918 document Canberra: Plan of City and Environs, the suburb is shown as an isosceles triangle with two equal length roads leading from Capital Hill to Yarralumla Bay and Clianthus Centre respectively. The latter road is now to location of the arterial Adelaide Avenue, and Yarralumla Bay and Clianthus Centre was to be joined along a north-south axis by Novar Avenue (originally to be named Mountain Way), extending all the way to the future lake bearing Griffin's name. Griffin's vision was for Westridge to become a business centre with an urban waterfront and promenade, complemented by the bush surroundings. Griffin's design was based on a strict hierarchy with core services such as housing, communal space and facilities such health and education, and commercial space. These would be connected outward by boulevards linking to transport routes and trams. By 1928, there were over 130 people on the electoral roll for Westridge. The majority of the population consisted of men working at the brickworks and nursery. The suburb was gazetted as Yarralumla on 20 September 1928. In 1922, a workers' tent camp was erected on the eastern side of Stirling Ridge to house the men working on the main intercepting sewer. The following year saw the start of the construction of 62 small, four-room, unlined timber cottages, to be used as housing for the married tradesmen involved in the construction of the provisional Parliament House. Other camps were established at the eastern end of Stirling Park on the hills opposite modern Lotus Bay. The first of these was contractor John Howie's settlement (1922–1930), consisting of 25 timber cottages for his married men and timber barracks (Hostel Camp) for his single men. Two other single men's tent camps were established nearby—Old Tradesmen's Camp (1923–1927) and No 1 Labourers Camp (1924–1927). The men from Howie's worked on the Hotel Canberra and the others on the construction of the provisional Parliament House and nearby administrative buildings. The Stirling Park camps were known as Westlake to their new inhabitants, and previously "Gura Bung Dhaura" (stony ground) to the local Aboriginal people. In 1925, the population of this temporary suburb was 700. This represented roughly one-fifth of the total population of the Federal Capital Territory at the time. In 1956, the Department of Interior decided to clear the settlement
