The carvings are not graffiti or later additions; they were incorporated during construction, placed where a person inside the hut would encounter them at close range. The motifs are predominantly equal-armed crosses, some with expanded terminals, some enclosed within circles, and a few accompanied by concentric ring patterns. One stone near the base of the northwest wall has a thin outer crust of quartz, and the four circles carved into it have been picked through that white surface, creating a deliberate contrast. Another, the largest of the group at roughly 84 centimetres wide, carries a cross flanked by two cross-in-circle motifs at slightly different heights, with a small incised dot precisely where the arms meet.

The hut itself is a substantial piece of early medieval construction. Corbelled walling, a technique in which each course of dry-laid stone projects slightly inward until the courses finally meet overhead, creates a self-supporting roof without mortar. Here the walls average over two metres in basal thickness and still stand to one and a half metres internally. The plan is almost square inside but rectangular with rounded corners outside, a refinement that required corner slabs to be cut to the exact angle of the wall. A well-made lintelled entrance passage, just over two metres long, sits midway along the northeast wall; the scholar Westropp recorded two perforated slabs inside the entrance in 1912, noting that they had once held the posts of a door frame, and one remains in place. There is also a narrow lintelled opening in the southeast wall that Westropp read as a secondary doorway and the scholar Françoise Henry, writing in 1957, took to be a flue, a disagreement that has not been fully resolved. A second, less well-preserved hut abuts the south side of the earlier one, sharing its wall, and a feature in its northeast angle that Henry identified as part of a corn-drying kiln was later recognised as a simple lamb shelter. This hut is one of a group of five in the same area, roughly eighty metres southeast of a related site, and the whole cluster sits within a landscape of Iveragh Peninsula monuments that has accumulated across many centuries of use.
