The structure is small, circular, roughly 3.4 metres across, with its interior partly scooped into the natural slope on the western side. A single upright stone remains standing to the east, accompanied by a scatter of fallen stones, and the whole is supplemented by an annex extending eastward, measuring approximately 4 metres north to south and 3.6 metres east to west. Some of the stones defining the annex are still well embedded in the ground, though the southern edge has become very indistinct over time.

Hut sites of this kind are the physical traces of early settlement, typically small stone-built or stone-footed shelters used by farmers, herders, or in some cases early Christian hermits who sought remote coastal ground. The place name Disert is itself suggestive: derived from the Latin desertum by way of early Irish, it was used to describe a place of retreat or solitude, often associated with a hermit or a small religious community withdrawn from the world. Whether the structure here belonged to such a community or simply to a person working the land above the sea is not recorded, but the setting, perched above a rocky coast at the margins of the habitable terrain, lends itself to both readings. The combination of the main circular cell and the attached annex is a form found at other early sites across the west of Ireland, where modest stone enclosures were added incrementally to meet practical needs.
