Three gables break the south-western elevation, giving that face of the building a distinctly different character from the rest, where the roof is hipped, sloping away on all sides in the manner more typical of Georgian and post-Georgian rural houses in Munster. It is the kind of architectural inconsistency that tends to accumulate over time, suggesting additions or alterations made by different hands with different ideas about what the house should look like.

The building is a rectangular two-storey structure with entrance and view fronts each of four bays. The entrance front, on the south-eastern side, carries an off-centre doorway with a fanlight above it, a modest decorative flourish common in Irish vernacular and middling-gentry houses of the late eighteenth and nineteenth centuries. That asymmetry is compounded by the replacement of two original ground-floor windows on the right-hand side with a single large modern window, an alteration that sits visibly at odds with the original proportions. To the north, one- and two-storey stone-built farm buildings speak to the working agricultural life that would have been inseparable from a property of this kind, and a tower stands in the same direction, a separate structure recorded in its own right, hinting that the complex at Rockborough may have deeper or more layered origins than the existing house alone suggests.
