The building measures roughly six metres north to south and just over twelve metres east to west, an elongated rectangle aligned along its longer axis, with an entrance two metres wide sitting mid-way along the southern wall. That a doorway can still be identified with such precision speaks to how well the ground has preserved what stone and earth left behind.

The structure sits within the broader remains of Railstown, a deserted medieval settlement in the undulating farmland of south Tipperary. Such settlements, sometimes called deserted medieval villages or townland settlements, were once common across Ireland but were gradually abandoned from the late medieval period onwards through a combination of plague, land consolidation, and shifts in agricultural practice. At Railstown, this house was not alone; another building of the same type stands roughly twenty-seven and a half metres to the north, suggesting a modest cluster of domestic structures rather than a single isolated dwelling. The house lies fourteen metres south-south-west of a pond, which would have been a practical resource for any household and may help explain the precise positioning of buildings on this particular ridge top.
