That detail alone sets it apart. Corbelled drystone structures, built by laying flat stones in overlapping rings that gradually close to form a self-supporting dome or vault, are among the oldest building techniques in Ireland, and most of the ones that survive have long since lost their covering. This one has not.

The hut is sub-rectangular in plan, measuring roughly 2.3 by 2 metres across and standing 1.7 metres high, just enough to stand in, or nearly so. It has two wall niches, shallow recesses built into the thickness of the stone walls, likely used for storage or to hold a lamp. What makes the structure particularly interesting is its history within a history: the current hut was not built from scratch but was created by inserting a secondary wall across the interior of an earlier, larger structure. That earlier building was pear-shaped and measured approximately 4 by 2 metres, and its outline can still be traced. The smaller, roofed space is effectively a room carved out of a predecessor. J. Cuppage documented the site in the 1986 Dingle Peninsula archaeological survey, "Corca Dhuibhne", the foundational reference for this part of the Iveragh and Dingle coastline.

The location, on steep rocky terrain in a mountain hollow on the Dingle Peninsula, means the approach is unlikely to be straightforward. Com an Lochaigh is a coum, the Irish word for a glacially carved mountain hollow, and the ground around it tends to be rough and uneven. The hut sits low in the landscape, and the retained roof means it may read from a distance as little more than a heap of stone, requiring a closer look to resolve into the structure it actually is.
