The homestead was built in 1929 to function as an outstation on Stapleton Station, then owned by Harry Sargeant and his family. It was constructed using bush timber (cypress pine) and iron in the form of a large central room that could be closed up with verandahs around the edges. Blyth Homestead is one of the few extant examples of this type of building which was formerly common on NT pastoral leases.

The Homestead site contains tangible and well-preserved remnants of both pastoral and mining activities. The isolated location necessitated the occupants to be virtually self-sufficient with a fruit and vegetable garden, milking cows and meat. A sawmilling plant was used to cut timber needed. Their income was supplemented by alluvial and reef tin mining to the east of the homestead, the products of which had to be carted by buckboard along a self-made track over the Finiss River.

The simple bush architecture of the homestead and the opportunistic nature of the mine workings illustrate the harsh conditions under which the Sargeant family lived.
