They cut a terrace into a hillside on the Iveragh Peninsula in south Kerry, lined its southern edge with drystone masonry to hold the ground in place, and then built two circular stone huts side by side, connecting them with a low internal passage. The result is a pair of conjoined corbelled structures, corbelling being a technique in which courses of stone are progressively cantilevered inward until they meet at a roof, requiring no mortar and no timber. That this method was used here tells us something about the builders' resources and their intentions, though it tells us rather less about when they lived or why they chose this particular patch of ground.

The two huts differ noticeably in scale and condition. The eastern one is roughly 3.9 metres by 3.7 metres internally, with walls surviving to around 1.2 metres in height; its original south-eastern entrance is still legible, marked by a pair of upright stones at the inner end of an opening 0.8 metres wide. A lintelled passage connects it to its western neighbour, a tight affair just half a metre high and wide, and 1.3 metres long, low enough that anyone using it would have had to crouch or crawl. The western hut is the larger of the two, at 4.3 metres in internal diameter, but it has been considerably modified and rebuilt at some point, which complicates any reading of it. What may be the most revealing detail survives at its base: the remnants of three mural chambers set into the internal wall-face. These small recesses, tucked into the thickness of the wall, appear to be original features, and their presence suggests the western hut was once a more elaborate structure than it now appears. The current entrance is a gap at the north, but the basal evidence hints that the original doorway, like that of the eastern hut, faced south-east.
