The structure is corbelled, meaning its courses of drystone are laid so that each row projects slightly inward over the one below, gradually closing the space until a roof of overlapping slabs can cap the whole thing. It is a technique of considerable ingenuity, producing a watertight interior from nothing but careful geometry and the weight of the stone itself.

The hut is subcircular in plan, measuring 2.4 metres across internally, which gives a sense of how intimate, or how confined, the space would have been for whoever used it. The walls reach a maximum height of 1.9 metres, tall enough to stand in, at least near the centre. A narrow entrance, just 0.55 metres wide, faces east and is now partly blocked. The structure sits in Baile an Lochaigh, in the Corca Dhuibhne region, and was documented by J. Cuppage in the 1986 Dingle Peninsula Archaeological Survey, a methodical effort to record the extraordinary density of early and medieval remains that survive across this westernmost part of Ireland, where Atlantic weather and sparse later development left much undisturbed.
