What makes it quietly unusual is not just the layering of ecclesiastical and domestic history on a single plot, but a small technical detail: when surveyors examined the structure in the nineteenth century, they could still observe the wicker centring used during construction. Centring is the temporary framework built to support an arch or vault while the mortar sets, normally removed once the stonework can bear its own weight. That traces of the wicker survived at all, embedded or visible within the fabric of the vault, gives the ruin an almost accidental intimacy, a glimpse into the practical methods of whoever raised the building sometime in the sixteenth or seventeenth century.

The Ordnance Survey Letters of 1837 record that the structure stands on the site of a former monastery, a detail that immediately complicates any straightforward reading of the building as simply a domestic residence. The house is rectangular in plan, roughly 12.80 metres long and 9.50 metres wide, with steeply pitched gables and a chimney out-shot at the south-west corner. Two plain windows, both damaged, survive in the north gable. The walls are built of randomly coursed rubble masonry, with roughly dressed quoins at the corners, quoins being the larger, more carefully shaped stones used to reinforce and define the edges of a wall. The OS Letters also noted a series of steps that once descended to the ground floor, though these have since disappeared entirely. When development was proposed on the periphery of the site in 1990, an archaeological clearance was carried out across the areas to the north, east, and south. No structural features emerged, but two sherds of sgraffito-type pottery were recovered alongside a portion of a large quernstone, a hand-operated grinding stone, suggesting some level of domestic or agricultural activity in the vicinity.

The site lies in Killininny, south County Dublin, and because it occupies what was once monastic ground, the surrounding landscape may reward careful attention even where the standing remains are limited. The ruined walls are the most legible feature, and the north gable with its surviving window openings offers the clearest sense of the original scale. The vault traces are on the ground floor, though access and visibility will depend on the condition of the interior at the time of any visit. The two sherds of sgraffito pottery found in 1990, a type characterised by incised decorative lines through a slip coating, are modest finds, but they place ordinary human activity here across a considerable span of time.
