What reads from the front as a mid-nineteenth-century country house is, at its core, a structure built around 1720, and early to mid-eighteenth-century estate maps confirm it in some detail: a two-storey, five-bay building with a central door, three dormer windows, a hipped roof with chimneys at either end, and what appear to be wings on either side. The Victorian front, added around 1860, effectively masked all of this. The older section behind it is of double pile construction, meaning the building is two rooms deep from front to back, a plan associated with more substantial domestic architecture of the period.

The interior repays closer attention than the exterior might suggest. The carved staircase draws comparison with Damer House in Roscrea, one of the finest early eighteenth-century town houses in Ireland, and shares its most distinctive feature: the balustrades rise directly from the treads of the steps rather than from a closed string, a detail that gives the stair an open, almost floating quality. Elsewhere in the basement, corner corbel supports, stone or timber brackets projecting from the walls to carry a load above, survive in two separate rooms, though what they once supported is no longer clear. A coin dating to around 1690 was found behind a fireplace mantle in a cottage in the yard, a small object that reaches back to an era before the house itself was built. The Civil Survey of 1654 to 1656 records the site as the castle of Castleloghy, with a thatched tenement standing opposite it, and lists one Donogh O Bryen of Bellanaha, described as an Irish Papist, as proprietor in 1640. The designation reflects the legal language of the Cromwellian period, when Catholic landowners were routinely catalogued in such terms. Between that castle and the Georgian house that replaced or absorbed it, the site holds a longer sequence of occupation than its present appearance lets on.
