The building sits at the boundary between improved pasture and rougher ground, the kind of liminal position that often signals the edge of former settlement, where cultivation gave way to something wilder. What remains is a rectangular footprint measuring roughly eight metres east to west and five metres north to south, with the collapsed wall material spread to a width of about ninety centimetres and rising barely twenty centimetres above the surface. It is subtle enough to walk past without registering.

The house is one element in a small cluster of medieval remains. Just seven metres to the south sits a square cashel, a type of stone-walled enclosure used in early and medieval Ireland to define a farmstead or protected domestic space, and this one is described as moderately well preserved. The relationship between the two structures suggests the house and the cashel belonged to the same working landscape, possibly the same household across generations. A second rectangular house has been built into the north-west corner of the cashel itself, and the building at Lisheeneagh has its own smaller annexe, a narrow structure measuring four metres by just under one and a half metres, tucked into its north-east corner. That kind of addition, tight and purposeful, points to practical expansion rather than grand ambition. A loose architectural fragment lying just south of the house's southern wall hints that the building once carried some dressed or shaped stonework, though what form it originally took is no longer clear.
