The structure is modest almost to the point of invisibility: just two metres across internally, with walls that survive to no more than half a metre on the northern side and average around forty centimetres in width. A possible entrance opens to the south, which would have offered some shelter from the prevailing weather. What makes it quietly arresting is the scale. Two metres of interior diameter is barely enough to lie down in, let alone stand comfortably, and the thinness of the surviving walls suggests something temporary or seasonal rather than a permanent dwelling.

The site was documented by F. Coyne in a 2006 upland archaeological study covering Mount Brandon and the Paps, two of Kerry's most significant mountain areas. Published by Kerry County Council in association with Aegis Archaeology under the title "Islands in the clouds", the survey set out to record the scattered archaeological remains of these elevated landscapes, places that tend to be overlooked precisely because they sit outside the more visited lowland zones. Hut sites of this kind are often associated with booleying, the seasonal practice of moving livestock to higher pastures in summer, with herders living in temporary shelters close to their animals. Whether this particular structure fits that pattern is not confirmed, but the combination of its small size, thin walls, and upland position is consistent with such use.
