Attunga, Toorak Gardens

It was built on 4.5 acres (1.8 ha) at 120 Kensington Road, in what was then Rose Park, (an inner eastern suburb of Adelaide, South Australia).

Containing 14 rooms, the two-storey house is the largest and most extravagant mansion built in the area that became known as the suburb of Toorak Gardens.

[b] While maintaining and paying particular attention to the property, von Rieben eventually settled at "Pomona" at Mt Lofty in the Adelaide Hills.

In November 1943, the council adopted the committee's recommendation to spend up to £100,000 on the building of a hospital, which was intended to be the district's principal memorial to honour Burnside's war dead.

[4] By April 1949, the first stage of the conversion of the mansion had been completed, with Attunga having been converted into a convalescent hospital caring for 21 patients.
