What makes it quietly peculiar is the way it came to exist at all: rather than being built as a freestanding structure, it borrowed one of its walls from something else entirely.

The hut measures roughly 3.75 metres east to west. Its curved side is formed by a drystone wall, a type of construction using dry-laid stone with no mortar, running about a metre thick and still standing to around 0.8 metres in height. The straight western side, some 3 metres long, is not a wall built for the hut at all but simply the eastern face of an adjacent cashel, a type of stone-walled ringfort common across early medieval Ireland. Whoever built the hut recognised that the cashel wall was already there and made it do double duty. The base of the drystone walling is now in a ruinous state, and the interior has filled over time with rubble and encroaching vegetation, leaving the D-shape legible in outline but emptied of whatever domestic detail it once contained.
