Three sides of a rectangular shape survive, defined by ridges of earth and stone roughly 0.8 metres high and 0.5 metres wide. The fourth side, to the west, has either collapsed or was never fully enclosed in the same way. What remains is modest almost to the point of invisibility, the kind of feature that rewards careful looking rather than a casual glance.

The structure sits within a cashel, a type of early Irish stone enclosure, typically circular or oval, built to define and protect a farmstead or settlement. The cashel at Rathmorrissy is recorded separately, and this probable house site occupies its north-west quadrant. Beyond that spatial relationship, the date of the dwelling is unknown. The indeterminate dating reflects a genuine archaeological uncertainty rather than a lack of investigation; without excavation or datable material finds, structures like this can belong almost anywhere within a broad sweep of Irish history, from the early medieval period onward. The banks themselves, low and softened by time, give little away.
