The structure is modest by any measure, just three metres in diameter, with walls that were never particularly refined, built from rough stone stacked without mortar. What is quietly telling about it is the care taken to make it habitable despite the slope: the interior was cut nearly half a metre into the hillside on the south-east side, effectively levelling the floor against the natural incline. That small act of practical engineering is often the most human detail in sites like this.

Drystone hut sites of this kind, built without mortar and relying entirely on the weight and fit of the stone, are found across upland and marginal landscapes throughout Ireland. They are notoriously difficult to date without excavation, and their uses varied widely, from seasonal shelters for those tending livestock on higher ground, to more permanent habitation in periods when population pressure pushed settlement onto poorer land. The lower courses of the Garranes wall still protrude above the bog surface, which suggests that peat growth has gradually swallowed much of the structure over time, preserving what remains beneath a layer of waterlogged ground. A second hut site sits roughly 45 metres to the north-east, hinting that this was not an isolated structure but part of a small cluster of occupation, however temporary or seasonal that occupation may have been.
