The north wall is built directly into the natural rise of ground that divides the enclosure, a practical borrowing of the landscape that hints at a builder more interested in getting the job done efficiently than in formal construction.

The hut forms part of An Chathair Bhearnach, a cashel or stone-walled enclosure of the kind found across early medieval Ireland, typically dating from roughly the sixth to the twelfth century, though many were used across longer and more complicated timespans than that neat bracket implies. Where the walls survive to any height, the construction follows the drystone technique, with large upright slabs forming the basal course of the interior face, and smaller coursed stonework built on top of them. The southern wall, at 1.8 metres thick, is the most substantial surviving element, though the overall structure is described as poorly preserved, its subcircular outline now more readable as a pattern of tumbled and grassed-over stone than as a standing building. The archaeological survey of the Iveragh Peninsula, compiled by A. O'Sullivan and J. Sheehan and published by Cork University Press in 1996, provides the recorded measurements and layout that allow the hut to be understood within the broader context of the cashel it inhabits.
