Corbelling is an ancient building technique in which stones are laid in overlapping horizontal courses, each projecting slightly inward over the one below, until the courses meet at the top to form a self-supporting dome or roof with no mortar holding any of it together. The result, when it endures, is a structure of quiet precision, the geometry of survival rather than ornament.

This particular hut is circular in plan, with an internal diameter of around 3.25 metres and a surviving height of 1.88 metres, its walls roughly 1.35 metres thick. It opens northward onto an irregularly shaped enclosure measuring approximately 4.57 by 5 metres internally. The dimensions give a sense of the place: low, compact, built for function rather than comfort. The site was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a landmark piece of fieldwork that catalogued the remarkable density of ancient remains concentrated along this narrow finger of land reaching into the Atlantic. The hut sits around 100 metres south of a related monument, suggesting it formed part of a small cluster of structures rather than an isolated building.
