What makes it structurally curious is the way one of its walls was never built at all: a natural rock outcrop forms the straight side of the D-shaped plan, so the builder worked around the landscape rather than against it. The roof is corbelled, meaning each course of drystone walling projects slightly inward over the one below, gradually narrowing the space until the final slabs can bridge the gap entirely, without mortar and without timber.

The hut has a lintelled entrance less than a metre high and not quite half a metre wide, modest even by the standards of early Irish stone buildings. Directly east of the doorway there is a small window opening, roughly 23 centimetres tall and up to 55 centimetres wide, which would have admitted a narrow band of morning light. Structures of this corbelled type are found elsewhere on the Corca Dhuibhne peninsula, and while precise dating is rarely straightforward without excavation, the form has early medieval associations in this part of Ireland. The hut is recorded in J. Cuppage's 1986 archaeological survey of the Dingle Peninsula, which remains one of the most thorough regional surveys of its kind.
