It is modest almost to the point of invisibility, yet the care taken in its construction tells you something once was expected of it.

The building occupies the western end of the northern wall of a known enclosure, sitting inside rather than independent of it, which suggests it was either a later addition making use of existing shelter, or a purpose-built feature integral to the enclosure's use. It measures roughly three metres on its longer axis and two metres on the shorter, interior dimensions that would make it a tight fit for human habitation but reasonable for animal shelter, storage, or any number of agricultural uses common to rural Clare across many centuries. The walls are drystone and double-faced, meaning two parallel lines of stone with the gap between them filled or simply left, a construction method that produces a wall considerably more solid than a single-skin arrangement. At seventy centimetres wide and surviving to a height of one point two metres in places, the walls are thick relative to the interior space, which again points toward a functional rather than domestic purpose. The entrance faces the north-east.
