The structure is modest, roughly 5.7 metres north to south and 6 metres east to west, its walls surviving as a spread of stone about 1.6 metres wide on the eastern and southern sides. To the west, the definition breaks down entirely, leaving a gap of some 2.5 to 3 metres where the outline becomes guesswork. Only at the north do a few boulders interrupt the natural gradient of the slope, hinting at where a wall once held back the hill.

This hut sits within a cluster of similar structures on the slope below the stone rampart of the hillfort on Brusselstown Hill, itself part of the larger Spinans Hill hillfort complex. A hillfort is typically a defended enclosure, often of prehistoric date, bounded by earthen banks or stone ramparts and built on high ground for reasons that may have combined defence, storage, assembly, and status. The Spinans Hill complex is one of the more substantial such groupings in County Wicklow, and the presence of multiple hut sites arranged on the slope below the rampart suggests that people were not merely sheltering within the fort proper but living in something closer to a settlement outside or alongside it. The hut recorded here is catalogued as number 12 in the Grogan survey, indicating it is one of several individually documented within the cluster.
