The walls are mostly gone, reduced to low banks of compacted earth with stones protruding here and there, but the ground still holds the logic of a dwelling: a rectangular footprint, a doorway opening onto the north side, and the faint geometry of a plot that once organised daily activity around it.

The building sits within the broader remains of Railstown, a medieval settlement whose various components have been mapped across this stretch of undulating Tipperary farmland. The structure itself measures roughly 4.8 metres north to south and 9.7 metres east to west, oriented along an east-west axis, with an entrance about 1.1 metres wide set towards the western end of the north wall. The banks that define it vary considerably in their preservation. The north and south walls survive to an internal height of between 0.5 and 0.7 metres, while the eastern side is far more eroded, rising only about 0.22 metres on the interior. At the south-east angle, a tree has taken root where the bank has broken down entirely. The north wall of the building also serves a second function: it forms the northern boundary of a larger enclosed plot, roughly 24.4 metres by 17.5 metres, with traces of another possible structure at the plot's southern end. That double use of a single wall, serving both as house wall and enclosure boundary, is a compact piece of medieval practical thinking, the kind of arrangement that would have organised a household's working space around the building at its core.
