The outline is nearly circular, measuring 7.5 metres north to south and 6.2 metres east to west, with a level interior that sits slightly raised above the surrounding ground on its southern side. That modest rise is easy to overlook, but it speaks to deliberate construction: someone chose this exact flat terrace, at the base of a very steep slope, and shaped it into a habitable space.

The hut is one of several clustered on this south-facing slope, all of them sitting beneath the stone rampart of the hillfort that crowns Brusselstown Hill. Hillforts, which are enclosed settlements or gathering places defined by earthen or stone banks, are relatively rare in Ireland, and this one forms part of a considerably larger complex centred on Spinans Hill. The scale of that wider complex makes the domestic details here all the more interesting: within an elaborate landscape of ramparts and enclosures, people were also simply living, in circular stone-defined huts arranged along a sheltered slope. Just 5.5 metres to the west of this particular hut lies a separate enclosure, suggesting that the immediate area was organised and purposeful rather than incidental. The relationship between the hillfort's defensive or communal architecture and these smaller, more intimate structures is the kind of question that makes upland archaeology compelling without ever fully resolving itself.
