The foundation courses are all that remain of a rectangular hut near Keel, the walls themselves long since gone, leaving only their footing, averaging about 65 centimetres in width. The internal space measures roughly 6.1 metres along its north-west to south-east axis and 2.55 metres across, which is a narrow room by any standard. No doorway has been identified, which may simply mean that any timber or lighter structural elements have vanished without trace, or that the entrance lay on a side now too disturbed to read. The structure may be relatively modern in date, which places it in an odd category, too recent to carry the romance of antiquity, too ruined to tell us much about whoever used it.

More arresting than the hut itself is what sits roughly 150 metres to the south-west, on the bank of a small stream. A fulacht fiadh, a type of prehistoric cooking site found widely across Ireland, survives here as a horseshoe-shaped mound some 7 metres north to south and 8.5 metres east to west, standing 1.4 metres high. The classic interpretation of these monuments involves heating stones in a fire, dropping them into a water-filled trough to bring it to the boil, and using that trough for cooking or other heat-dependent tasks. The trough at this example is a sloping, roughly rectangular depression on the northern side of the mound, facing the stream, measuring about 3.4 metres long, 1.3 metres wide, and 45 centimetres deep. The mound itself is built from the discarded debris of repeated use, small fire-shattered stones and blackened earth with a notably high charcoal content, the compacted residue of many firings over what may have been a considerable span of time.
