The Nash family established themselves here by at least the 16th century, maintaining a castle on the site that would eventually give way to Georgian elegance. In 1740, they replaced their medieval stronghold with a country house that still stands today, representing a significant shift from defensive architecture to domestic comfort.

The house itself is a fine example of mid-18th century Irish country house design. Rising three storeys, it features a tripartite fanlighted doorway that welcomes visitors with characteristic Georgian symmetry. Inside, the craftsmanship of the era shines through; the hall ceiling boasts decorative plasterwork typical of the 1740s and 50s, whilst the staircase showcases the joiner's art with its carefully crafted gallery. These details mark it as the work of skilled artisans who understood both fashion and function.

After centuries of use and inevitable decline, the house received a careful restoration in the 1970s, preserving its historical features for future generations. The building stands as a testament to the Nash family's long presence in Limerick and the broader story of how Ireland's landed families transitioned from medieval fortifications to the refined country houses that dot the landscape today. Archaeological surveys from 2006 have documented the site, ensuring its place in Ireland's architectural record.
