It is a corbelled hut, a structure built by laying courses of stone so that each ring overhangs the one below until the gap closes at the top without any mortar or timber to hold it, and this particular example has survived the Atlantic weather in better shape than almost everything around it. It sits at the north-eastern end of the village, compact and complete, its original roof still doing the job it was built to do.

Despite its ancient appearance, the hut is relatively recent in origin. According to Stagles and Stagles, writing in 1980, it was constructed as an outbuilding around a century ago, meaning it was built and in use while the island community was still very much alive. Its dimensions are modest, a diameter of just over two and a half metres, a height of just over two metres, and walls three quarters of a metre thick, yet it includes a lintelled doorway and a window, details that give it more architectural intention than a purely functional store might suggest. The corbelling technique itself is one of the oldest building methods in Ireland, associated far more commonly with early medieval monastic structures or prehistoric passage tombs than with nineteenth or early twentieth century farm outbuildings, which makes its appearance here, in this practical and workaday context, quietly unexpected.
