It measures roughly two metres north to south, its curved wall reduced to a single collapsed course of drystone, and its southern side formed not by any human construction at all but by the vertical face of a natural rock outcrop. Whoever built this structure simply incorporated the geology into the design, letting the mountain do part of the work.

The hut sits within a wider network of relict field boundaries, the ghostly grid of an agricultural landscape that has long since been absorbed by rough hill pasture and peat. The surviving wall fragments give some sense of the original form: stones along the eastern wall are set upright, placed at right-angles to the line of the wall in a technique sometimes used to stabilise a boundary or add height, while those along the western wall have fallen and lie flat. The lower course stones still protrude through the bog surface, which is both what has preserved them and what makes them easy to miss from any distance. Drystone construction, which uses no mortar and relies entirely on the careful fitting of stones, was the standard building method across this kind of upland landscape for centuries, and structures like this one served a range of purposes, from seasonal shelters for those tending animals on high ground to more permanent small dwellings. An east-west section of one of the associated field walls runs immediately to the north of the hut, suggesting this was once a managed, divided, and worked hillside rather than the open rough pasture it appears today.
