The structure is modest even by the standards of ancient Irish settlement: roughly 5.3 metres east to west and 3.6 metres north to south, its walls now a collapsed ribbon of drystone, the remaining height little more than ankle level. Drystone construction, meaning walls built from dry-laid stone without mortar, was common across Irish uplands for centuries, its simplicity suiting the readily available local material. What lends this particular site a quiet specificity is the ground preparation involved: the western portion of the interior was deliberately cut into the slope to create a level floor, a small but telling effort that suggests the place was meant to be genuinely lived in, or at least regularly used, rather than thrown up in haste.

The hut does not sit in isolation. It lies within a network of relict field boundaries, the ghostly outlines of an agricultural landscape that was once actively managed and has since been abandoned to the mountain. One of those old field walls still abuts the northern arc of the hut externally, the two structures having grown together over time into a single tangled feature. A possible entrance, just half a metre wide, faces south, a sensible orientation on an exposed ridge. Two metres to the east, a second hut site survives in similar condition, suggesting that whatever community or activity this slope once supported, it involved more than a single structure.

The site sits in rough upland pasture, and the terrain of Mangerton's southern slopes is uneven and wet underfoot for much of the year. The hut itself is easily missed at ground level, its walls having collapsed to a height of around 40 centimetres, and it reads more clearly as a landscape feature when viewed from a slight distance, where the oval outline and the surrounding field system begin to resolve into a pattern.
