The remains of a hut site, roughly 2.2 metres across on its longest axis, sit in a sheltered hollow that slopes gently eastward, the wall still standing around half a metre high and sixty centimetres thick, its curved arc meeting a straight southeast side to form that characteristic flat-backed D. A gap in the wall on the eastern side is likely where the entrance once stood, a small opening through which someone long ago passed in and out of a space barely larger than a modern bathroom.

What makes Coonane quietly unusual is not the single structure but the cluster. Another hut site lies approximately 30 metres to the northeast, and a third sits only 6 metres to the south, all of them set within a wider network of relict field boundaries, the low, overgrown traces of a landscape that was once organised and inhabited. Together they suggest a small settlement rather than an isolated shelter, people making use of this sheltered hollow with some degree of intention. The bog has since crept over much of what they left behind, preserving the walls by surrounding them rather than burying them, so that the stonework still protrudes above the surface. Hut sites of this kind are generally associated with early medieval or prehistoric occupation in Ireland, temporary or seasonal encampments as much as permanent dwellings, though dating a structure from its shape and materials alone is rarely straightforward.
