The origin of its name is unknown . It was built as a temporary measure, to be occupied by whoever was the Prime Minister "until such time as a monumental Prime Minister's residence is constructed, and thereafter to be used for other purposes". The original "Prime Minister's cottage" was built in 1926--1927 at a base cost of £ 25,000 and an eventual total of "£ 28,319, including the landscaping of 2.8 hectares of grounds, construction of a tennis court and croquet lawn, and furnishing and interior decoration". The architects were Percy A. Oakley and Stanley T. Parkes of Melbourne; the builder was J.G. Taylor of Sydney . Ruth Lane Poole of Melbourne was responsible for interior design and furnishing, as she had been for the Governor - General's residence, Government House . The Lodge was intended as one of a set of three official residences, the others to be for the presiding officers of the Parliament of Australia (the Speaker of the House of Representatives and the President of the Senate), but the others were never built . </P>
