Wallcliffe House was a heritage listed two-storey stone, shingle and corrugated iron homestead located near Prevelly and the mouth of the Margaret River in Western Australia.

[1] It was built by George Holland Knapton for owners Alfred and Ellen Bussell (née Heppingstone) between 1857 and 1865 in the Victorian-Georgian style,[2] using limestone quarried on the property and pit-sawn jarrah.

Before moving to Wallcliffe, the Bussells lived at "Ellensbrook", a 4-hectare (10-acre) holding several miles north of the Margaret River on the northern edge of their lease.

[3] In 1876, Grace Bussell and Sam Isaacs helped save the lives of around 50 people as the SS Georgette sunk off nearby Calgardup Bay.

In 1902 Gale onsold the estate to A. C. R. Loaring and Neil McLeod, who later sold Wallcliffe House and 16 hectares (40 acres) of land to Filumena Terry (née Bussell) in 1910/11.
