The walls have collapsed inward over time, spreading rubble across the interior, and what remains barely rises above ankle height in places. Yet the footprint is still legible: a rectangular structure measuring roughly 6.2 metres north to south and 4.8 metres east to west, sitting just 14.5 metres northwest of the graveyard's northwest corner.

The building's precise purpose is uncertain, though it has been identified as a possible house site. A gap on the east side, about 1.6 metres wide, may mark an original entrance. The proximity to a church and graveyard is not unusual in Irish archaeology; ecclesiastical enclosures frequently attracted associated domestic or ancillary structures, whether for a resident cleric, a caretaker, or some other function tied to the religious site. What the building's relationship to Aharney church actually was, and when it fell out of use, the surviving remains do not say. The walls, now reduced to grassy ridges between roughly 0.1 and 0.5 metres high, have lost whatever above-ground evidence might once have answered those questions.
