A cashel is a stone-walled enclosure of early medieval origin, typically circular, used to protect a farmstead or dwelling, and this particular house site was built directly against its southern perimeter wall, sheltering in the lee of that boundary as though tucked in for protection.

The structure is defined by a wall footing, the lowest surviving course of a former wall, measuring roughly 1.7 metres wide and still standing between 0.3 and 0.7 metres high in places. Its interior dimensions are notably irregular: around 7.2 metres along the northwest to southeast axis but only 2.6 metres across from northeast to southwest, giving the floor plan a distinctly elongated oval shape rather than a rounded one. This asymmetry, combined with its attachment to the cashel wall, suggests a building that made deliberate use of existing structure, perhaps sharing a wall or simply wedging itself against one for stability or warmth. The date of the house is not known with any precision, which is itself a common situation with rural vernacular buildings of this kind; without datable finds or documentary records, such sites resist easy classification.
