What makes it worth attention is its construction method: the walls are built using a corbelled drystone technique, whereby courses of unmortared stone are laid so that each one projects slightly inward over the one below, eventually closing the roof without any need for timber or mortar. The surviving structure is semicircular in plan, roughly 3.5 metres across and still standing to about 1.2 metres in height, with walls approximately 1.25 metres thick. At the eastern interior, there appears to be a wall-niche, a small recess built into the fabric of the wall, which could have served any number of domestic or devotional purposes.

Corbelled huts of this type are found across the Iveragh Peninsula and the broader landscape of south Kerry, a region that preserves an unusually dense record of early settlement. The technique itself is ancient, appearing in Irish contexts from the prehistoric period onward, and was still being used by communities living close to mountain pasture well into the medieval and early modern periods. The thickness of the walls at Raheens, relative to the modest interior diameter, is characteristic of structures built to endure wind and damp rather than to accommodate much more than one or two people seeking shelter. Whether this was a shepherd's temporary refuge, a more permanent habitation, or something else entirely is not recorded.
