What survives is a stone hut measuring about four metres in diameter, its walls reduced to a low, grass-covered bank of collapsed material no more than 30 centimetres high and about 1.4 metres wide at the base. It sits a little to the north-west of centre within a univallate rath, which is an enclosure defined by a single earthen bank and ditch, a form of enclosed settlement common across early medieval Ireland and typically associated with farming families of some local standing.

The hut is recorded as a subsidiary feature of the rath at Knockglass Beg, documented as part of J. Cuppage's 1986 archaeological survey of the Corca Dhuibhne region, which covered the Dingle Peninsula in considerable detail. The site sits within a landscape that has accumulated layers of human activity over many centuries, and the pairing of a rath with an internal stone structure like this one is consistent with domestic occupation, though the precise period of use is not recorded in what survives of the site description. The modest dimensions of the hut suggest a single-roomed structure, perhaps used for sleeping, storage, or sheltering animals, adjunct to whatever daily life the enclosure once organised around itself.
