It is a modest thing, measuring just 2.4 metres long and 2.3 metres wide, constructed in drystone, meaning its walls were laid without mortar, relying entirely on the careful fitting of stone against stone. The opening faces south, which in a climate like Connaught's is the practical choice for light and shelter from prevailing weather.

Beyond its dimensions and orientation, the record is spare. What can be said is that drystone hut sites of this kind represent a broad tradition of vernacular construction in the west of Ireland, where limestone was abundant and accessible, and where people built close to or into the landscape rather than imposing upon it. The bluff itself does much of the structural work, providing a rear wall that no amount of drystone craft could better for solidity and insulation. Whether the structure served as a seasonal shelter, a place for a herdsman watching livestock on upland ground, or something else entirely, the notes do not say. Paul Gosling's archaeological inventory of West Galway, published in 1993, recorded it without elaborating on a date or a specific use, which is itself a kind of answer: these small shelters were common enough to be practical, and anonymous enough to resist easy classification.
