Only three upright stones at the north-east remain above the surface with any confidence; the rest of the structure announces itself through stones that barely break the turf, hinting at a complete circuit below. The hut measures roughly 2.3 metres in diameter, which is small even by the standards of early Irish vernacular structures, the kind of single-cell stone shelters associated with seasonal activity, monastic retreat, or pastoral land use across early medieval and earlier periods in Ireland.

The site at Knockaneyouloo was documented by archaeologists A. O'Sullivan and J. Sheehan in their survey of the Iveragh Peninsula, published by Cork University Press in 1996. That survey catalogued hundreds of sites across one of the most archaeologically dense regions in Ireland, a landscape where ringforts, standing stones, and early ecclesiastical remains cluster across the hills and valleys of south Kerry. This particular hut, modest in scale and now largely subterranean in character, represents the quieter end of that spectrum, the sort of site that rarely draws attention but which speaks to the ordinary rhythms of life and labour on the hillside. Its precise date remains unestablished from the available record, which is not unusual for unexcavated surface features of this type.
