Rectangular in plan, built from drystone walling without mortar, and measuring just 2.45 metres by 1.55 metres with walls rising to about 1.3 metres, it is barely large enough to shelter a single person. What makes it quietly arresting is the detail in one corner: a primitive fireplace, suggesting that whoever used this place did so over time, returning to it, relying on it.

The structure is thought to have been a booley-hut, a type of temporary seasonal shelter associated with the old Irish practice of booleying, or buaile in Irish, whereby cattle and their herders moved to upland summer pastures. Young people, often women and girls, would accompany the animals to higher ground during the warmer months and live in rough shelters while the lower fields recovered. These huts were built quickly and simply, intended for repeated seasonal use rather than permanence, which is part of why so few survive in recognisable form. The site at Acres, documented in J. Cuppage's 1986 archaeological survey of the Dingle Peninsula, fits this pattern well: positioned on elevated ground with a westward view over Minard Bay, it would have offered both visibility across the surrounding terrain and a degree of shelter from the prevailing wind.
