It is a drystone hut, meaning its walls were constructed without mortar, stone laid against stone in a technique that appears across Ireland from prehistory through to the early medieval period and beyond. The structure is modest in scale, roughly 2.8 metres by 2.75 metres internally, with what appears to be an entrance on the western side. A rectangular annex, just 1.3 metres by 0.9 metres, is attached at the northern end, adding a small functional projection to what is otherwise a near-perfect circle.

The site sits within the townland of Cill Urlaí on the Iveragh Peninsula, one of the great fingers of land that reach into the Atlantic along the south-west coast of Kerry. This peninsula contains an unusually dense concentration of early remains, from clochán clusters to ogham stones, and small huts of this kind can be difficult to date without excavation. They might belong to early Christian hermitic traditions, to seasonal pastoral activity, or to periods considerably later. The annex at the north is a detail worth noting; such additions sometimes served as storage spaces or animal shelters, though here no further function has been recorded. What survives is the bare geometry of the thing, its dimensions and orientation, and the fact of its presence on the hillside.
