There is no stonework, no hearth, no dropped object to tell us who used it or what for. What remains is essentially a conversation between soil and absence.

The structure sat within a larger enclosure and was recorded during excavation that year, led by work published under Noonan's name in subsequent reports. The building was roughly circular, about 5.1 metres in diameter, and built using a technique known as slot-trench construction, in which a narrow, shallow trench is cut into the ground to receive the base of a timber wall or wattle screen. Here the trench was between 22 and 27 centimetres wide and only 5 to 11 centimetres deep, best preserved along the northern, eastern, and western arcs. Along the southern arc, a gap of 2.2 metres in the trench most likely marks where an entrance once stood. Two post-holes inside the structure, set a metre apart, probably held upright timbers supporting a roof, while six further post-holes outside the wall line may have braced the structure against the elements. Despite careful excavation, no hearth was identified and no finds were recovered from the deposits, leaving the building's date, purpose, and occupants entirely open.
