The building is modest in scale, nine metres long and just under five metres wide, and its walls were constructed in a technique common to the region: limestone blocks set on edge to form facing stones, with a rubble core packed between them. Drystone construction, which uses no mortar, relies entirely on the careful selection and placement of stone, and the Aran Islands provided abundant raw material in their fractured limestone pavements. The structure is poorly preserved for the most part, though the south-eastern corner survives in better condition than the rest.

No date has been firmly established for the building, which places it in a frustratingly broad category of vernacular or pre-modern stonework that resists easy classification. A second house of similar character lies a short distance to the west, suggesting that what survives here is not an isolated structure but a fragment of something once more coherent, perhaps a small settlement cluster. The site was noted by O'Flanagan in 1927 and later by Tim Robinson, whose meticulous mapping of the Aran Islands brought a great deal of overlooked archaeology to wider attention. The adjacent mound has not been assigned a definitive type, meaning it could represent a burial feature, a natural limestone outcrop worked or modified by human hands, or something else entirely.
