Yaralla Estate

Yaralla Estate is classified by the National Trust as 'the most significant, suburban Edwardian estate in New South Wales'. Situated in Nullawarra Avenue, Concord West, Yaralla Mansion was the former home of Eadith Campbell Walker. Her father, Thomas Walker, banker and philanthropist, commissioned Edmund Blacket to design the large two-storey building with four-storey tower, in the 1860s. The grounds of Yaralla covered over 100 acres (40.4 hectares), part of a land grant to convict Isaac Nichols, the colony's first postmaster, and was acquired from his sons by Thomas Walker in the 1840s in lieu of a bad debt.

Yaralla is situated on the Parramatta River extending from the bay opposite Mortlake to Concord West, and edges Major's Bay, Yaralla Bay and part of Bray's Bay, where the Rivendell section is located. It gently slopes up from the river to Concord Road. The top sections were sub-divided in 1908, 1912, and 1922, becoming estates of Federation and Californian bungalow homes built for soldiers after World War I.
