Corbelling is an ancient construction technique in which courses of stone are laid so that each projects slightly inward over the one below, gradually closing the space until the structure forms a self-supporting domed or vaulted roof, with no mortar and no timber required. The result here is a roughly square interior, measuring approximately 2.9 metres by 2.5 metres, with walls around 1.2 metres thick and a surviving height of just 1.35 metres. It is not a grand space, but it is a considered one.

What lifts this structure beyond the ordinary is the detail of its interior. Two wall-niches, each spanned by a stone lintel, are set into the northern wall, the kind of feature that suggests habitual use rather than hurried shelter, perhaps for storing small tools, a lamp, or food kept away from damp ground. The entrance faces south-east, a sensible orientation that limits exposure to the prevailing westerly weather. Immediately outside the entrance, to the south-east, a second lintelled chamber adjoins the hut, identified in archaeological survey work on the peninsula as a probable lamb shelter. To the east, a sheepfold completes the picture of a small pastoral working complex, the whole arrangement oriented around the seasonal routines of farming in high ground. The survey of the Iveragh Peninsula compiled by A. O'Sullivan and J. Sheehan, published by Cork University Press in 1996, recorded the site as part of a broader upland landscape dense with similar evidence of early agricultural and domestic life.
