The homestead is a single storey, rectangular building measuring about 6.9m x 10.6m with a pitched roof consisting of a timber roof frame and corrugated metal roof sheeting, mudbrick walls, concrete floors, surrounded by a 2.7m wide verandah supported by concrete posts. The building consists of three rooms, each measuring about 3.1m x 6.3m; one is used as a bar/kiosk, and the remaining two rooms are currently empty.

The Banka Banka mudbrick homestead is of significance for its architectural, historical and social values. Although partly reconstructed in 2001, the building is of architectural interest for its extensive use of mudbrick. It therefore represents an unusual construction material and technique for pastoral homesteads of this era.

The mudbrick homestead has substantial social value for its associations with the Wards, particularly Mrs Mary Ward, known as the ‘Missus of Banka Banka’, who was renowned for her hospitality as well as her work with Aboriginal families and children, particularly in the area of education. Together the Wards made a substantial contribution to the development of the NT in the mining and pastoral sectors through their ownership and development of the Blue Moon mine and Banka Banka station.
