Moated sites, common across medieval Ireland, were enclosed homesteads surrounded by a water-filled or dry ditch, typically associated with Anglo-Norman settlement from the thirteenth and fourteenth centuries. This structure sits off-centre towards the northern end of one such enclosure, a placement that hints at deliberate spatial planning within the wider site rather than casual or opportunistic building.

What remains is a rectangular footprint, roughly nine metres north to south and four metres east to west, defined by grass-covered rubble walls that survive to a height of only five to ten centimetres in places, with a wall thickness of around half a metre. A shared internal wall running roughly east to west divides the building into two compartments: a larger northern room of approximately four and a half by two and a half metres, and a slightly squarer southern room of around three by three metres. The ground level inside the structure matches the general interior level of the moated site, suggesting no significant subsidence or later disturbance has altered the relationship between the two features. To the west of the northern compartment, a large depression measuring roughly three and a half metres by two metres adds a further detail that remains unexplained; it may represent a collapsed cellar, a storage pit, or simply later ground disturbance. The date of the building is not known with any certainty, and no documentary record has been attached to it.
