The Residency Museum in York, Western Australia is a single-storey, heritage-listed building in the Victorian Georgian style.

The oldest section was built from hand-made bricks that bore the stamp of the broad arrow, meaning they were the property of the Crown, but which came to represent structures constructed by convicts.

In 1867, after several complaints to the colonial governor about the lack of suitable official accommodation for himself and his family, Resident Magistrate Walkinshaw Cowan moved from his property at Mile Pool to the cottage.

In 1926, a bathroom, toilet and new verandah were added to the northern wall of the central court and the building became the Matron's Quarters.

"Temporary additions and lean-tos were removed and the building renovated as nearly as possible to [its state] when Walkinshaw Cowan was Resident Magistrate in the 1860s.
