One of them is still largely intact: a circular hut just 2.2 metres in diameter and 1.6 metres high, built using corbelled drystone construction, a technique in which stones are layered so that each course projects slightly inward over the one below, eventually closing the roof without mortar or timber. There is an entrance on the south-east side and a small niche set into the north wall, possibly for storage or for holding a light. The other two structures are far less preserved, surviving only as shallow depressions in the ground: a second circular form to the north, roughly 2 metres across, and an oval one entered from the south-west, measuring approximately 3.5 by 2.5 metres.

The site was documented by J. Cuppage as part of the Dingle Peninsula Archaeological Survey, published in 1986 under the title Corca Dhuibhne, a comprehensive study of the Corca Dhuibhne region that brought together records of the extraordinary concentration of ancient monuments found across this part of west Kerry. The Dingle Peninsula is unusually dense with early ecclesiastical remains, field systems, and stone structures of this kind, many of them associated with early medieval monastic or pastoral activity, though precise dating for individual hut sites is often difficult without excavation. The corbelled hut at Gleann Fán belongs to a tradition of building seen elsewhere along the western seaboard of Ireland, including the famous beehive cells of the Skellig Michael monastery further south.

The south hut is the one worth locating carefully. The wall niche, small as it is, suggests this was a space used with some deliberateness, not merely a temporary shelter. The two depressions to the north and west are easily missed without knowing what to look for, their outlines softened by vegetation and time.
