Most early Irish hut sites are roughly circular or oval, so the subtriangular plan of this one is quietly anomalous, its three-sided outline now barely legible beneath the encroaching vegetation. The walls, where they survive, stand around 1.3 metres high and run to about 1.5 metres thick, which points to construction intended to last, even if time and boggy ground have done their work since.

The interior holds a detail that lifts this from an ordinary ruin into something more puzzling. Set into the floor or lower wall is a lintelled opening, roughly a metre square, leading down into a souterrain. A souterrain is an underground passage or chamber, typically built from drystone walling and roofed with large flat capstones, and found across early medieval Ireland in association with settlement sites. They were used variously for storage, refuge, or ventilation of adjacent structures. This one is recorded as inaccessible, so what lies beneath remains unknown. The proximity to Lough Currane, a substantial lake on the Iveragh Peninsula, and the placename Termons, which derives from the Latin terminus and commonly denotes early ecclesiastical land boundaries in Ireland, suggests this corner of Kerry was once more actively settled and organised than its present quiet bogland appearance implies.
