The hut is modest in scale, averaging five metres across internally, with foundation walls that survive to around twenty centimetres in height and up to two metres in width. That width relative to the low surviving height suggests substantial original construction, the kind of thick-walled technique common in early medieval Irish stonework, where walls were built broad enough to provide insulation and stability against Atlantic weather.

The hut is recorded as abutting a neighbouring structure to its south side, which points to a settlement where buildings were arranged in close relation to one another rather than scattered independently. Circular huts of this type are characteristic of early Christian period habitation in Munster, often found within or beside enclosures, and their presence on the Iveragh Peninsula fits a wider pattern of small farming and monastic communities that occupied this landscape from roughly the sixth century onward. The site at Caherlehillan sits within a part of Kerry that has yielded a remarkable concentration of such remains, documented in the 1996 archaeological survey of South Kerry compiled by A. O'Sullivan and J. Sheehan.
