Thomas Brassey McIntosh managed the property for the partners, and c. 1882 constructed the two-roomed stone house now known as Old Westmoreland Homestead.

[1] When Westmoreland was taken up in the early 1880s, guerrilla warfare between the indigenous owners of the land and the occupying pastoralists was being waged throughout the Gulf country.

There are many conflict sites in the area, including Hells Gate (20 miles (32 km) south-east of Westmoreland), Massacre Inlet and Battle Creek.

The c. 1882 homestead on Westmoreland station was constructed with thick stone walls, inward opening doors, and few windows, to provide security for people and property during potential attacks by Aborigines.

The block comprised 100 square miles (260 km2), with rich creek flats, steep stony ridges and open forests of box, bloodwood and tea-tree.

[1] Old Westmoreland Homestead is located within the precinct of the present head station adjacent to dwellings, cold room, garages and workshops.

[1] The original two-roomed homestead is constructed from hewn sandstone blocks using ant bed mortar and fill.

[1] Internally, the building is divided into two rooms by a partition of hardwood framing and single-skin corrugated iron to ceiling height, the roof space open above this.

A later kitchen, 3 by 4 metres (9.8 by 13.1 ft), constructed of metal framing and cladding, is located on the south-western side of the homestead.

Old Westmoreland Homestead, constructed c. 1882, is important for its association with, and as rare surviving evidence of, early efforts to establish the pastoral industry in north-west Queensland in the second half of the nineteenth century, during a period of frontier violence.

Although there has been some adaptation the building remains a rare example of vernacular nineteenth century stone pastoral homesteads in Queensland.

Old Westmoreland Homestead exemplifies the simple dwellings established during nineteenth century colonial settlement in remote parts of Queensland.

The simplistic form of the building, and the use of local materials, demonstrates the principal characteristics of this class of place: nineteenth century pastoral property homesteads.

The place retains a high degree of aesthetic value generated by the picturesque qualities of the simple design and the rustic materials employed in the construction: sandstone for the walls; ant bed for mortar and flooring; corrugated galvanised iron to clad the roof; and rough-cut bush timbers for the verandah posts.
