Wallcliffe House, Wallcliffe Road, Margaret River, was built between 1855 and 1865, and Classified by the Trust in 1969. It was built by Alfred Pickmore Bussell, and had important historical associations with the early pioneering Bussell family, including Grace Bussell. The house was built in the style of an English cottage, with many dormer windows. It was originally roofed with jarrah shingles, but was later covered with corrugated iron. The building featured spacious rooms.
The building incorporated pit sawn timber, tall stone chimneys, extensive verandahs and a gabled roof with attics.
Wallcliffe House was destroyed by fire on the 25th of November 2011, when seasonal bush fires swept the Margaret River region. The National Trust was very fortunate that Ellensbrook was not also destroyed in the same fire.
