What they found, compressed into the footprint of a few proposed houses, was the partial outline of a circular structure roughly six metres across, its presence betrayed by five stake-holes arranged in what appeared to be the western arc of a post-built hut. The eastern portion of the structure lay beyond the excavation boundary and remains unexamined beneath what is now presumably a suburban street. A cluster of additional stake-holes along the northwest arc may represent some external feature associated with the building, though their relationship to the main structure is uncertain.

The site sits within the historic town of Glanworth, southwest of the medieval friary known as Rock Abbey, and the finds point towards a late medieval date. A pit recorded inside the hut, designated F133 by the excavating team, has been dated to the late 13th century, and a second undated pit was also found within the same area. The proximity to a second hut site, excavated separately and lying only around 25 metres to the northwest, strengthens the case for a medieval date. The excavator, Cleary, noted in a 2007 report that the late 13th-century pit and this possible hut may well have been in use at the same time as that neighbouring structure, suggesting the two formed part of a small cluster of medieval occupation rather than isolated incidents of activity. Post-built structures of this kind, where upright timbers were set into individual holes rather than a continuous foundation trench, were a common form of vernacular building throughout medieval Ireland, and their identification depends almost entirely on the pattern and spacing of those voids left in the ground long after the timber has rotted away.
