The structure measures roughly eight metres long and six and a half metres wide, with walls nearly two metres thick, the sort of substantial construction that suggests permanence rather than anything temporary or incidental.

What makes it worth pausing over is precisely what cannot be said about it with confidence. Its date is unknown, and it has only tentatively been identified as a house site, meaning the people who recorded it were careful not to claim more than the stones themselves reveal. It sits in the south-southeast sector of the cashel, abutting its walls, which raises the possibility that the two structures were related in some way, one perhaps built in the shadow or shelter of the other. Whether the house came first, or grew up against an already-ruined enclosure, remains an open question. The walls are thick enough to have belonged to a building of some consequence, though without excavation, the interior arrangements and the period of occupation stay out of reach.
