The hut is modest even by the standards of ancient Irish shelters, measuring just 3.7 metres in diameter, and what survives is essentially its foundation: the base courses of a drystone wall, a building technique using stones laid without mortar, here just 0.3 metres high and 0.6 metres thick. A few stones protrude above ground level where the grass has not yet claimed them entirely, but most of the circuit is embedded in the bog itself.

Blanket bog is an unusually good preservative, and structures like this one can be difficult to date without excavation. Circular hut sites of this kind appear across upland Ireland and are associated with a broad range of periods, from the Bronze Age through to early medieval times, often connected with seasonal farming or pasture use in areas that were once more open and workable than they appear today. What gives the Drom site a little extra context is the presence of a field boundary wall roughly seven metres to the west, part of a wider network of enclosures in the area. The hut and the field system likely functioned together, suggesting this boggy hillside once formed part of a working agricultural landscape, however temporary or seasonal that use may have been. The east-facing slope on which it sits would have caught morning light and offered some shelter from prevailing westerly weather.
