Leuralla was built for the independently wealthy yachtsman and big-game fisherman Harry Andreas, his wife Alice and their young family. Harry and Alice Andreas lived at Leuralla until after World War II. In 1928, Clive Evatt married Marjorie Andreas, a daughter, of Harry and Alice, and the Evatt family connection to the property began. Clive Evatt Jnr, an Andreas grandson, managed the property. Clive Evatt and his wife, Elizabeth Evatt, are the founders of the present museum. They are responsible for the exhibition of H.V. Evatt memorabilia and for the toy and railway collection displayed in various buildings. Herbert Vere Evatt was Clive Evatt Snr's brother but had no particular connection with Leuralla and had a home of his own in Leura.
The house and outbuildings
In 1903 a house, known as Leuralla, was built on the current site but was destroyed by bushfire in 1909. Between 1910 and 1914 the present house was built and the design was influenced by the work of Frank Lloyd Wright. The house is an example of an early 20th Centurypermanent residence for a wealthy family. It is an imposing two-storey house set in extensive grounds in the Federation Free Classical style and is notable for its entry portico and stair, symmetry, and bracketed cornice. The walls and chimneys are rendered and the building is on a rockfaced sandstone base. Leuralla has a hipped roof with short projecting hipped wings on the southern and northern sides. The wide external sandstone staircase which has twin flights from the ground under a single storey portico. The portico is topped by a first floor balcony with balustrading. Doric columns complement the entry and the front door is multi-paned and has sidelights. There are symmetrically placed hipped roof bay windows on the northern and southern sides of the portico. The roof is covered in slate and ridged in terracotta. The garage has Federation Anglo-Dutch style influences and its walls are shingled with a weatherboardspandrel. There is a single-storeyed sandstone outbuilding with a gabled roof on the Olympian Parade side of the grounds.
The garden and amphitheatre
Andreas established an exotic garden from his earliest ownership of Leuralla and much of it was saved from the 1909 bushfire. It was redeveloped around the 1914 house and is still 5 hectares in size. A formal garden lay out was used originally by Andreas and later Paul Sorensen improved the garden overall. There is a sculpture garden on the south side of Olympian Parade. The amphitheatre on the edge of the escarpment takes advantages of its spectacular setting overlooking the Jamieson Valley.
