The house had not even reached a century of age before it began its long collapse, and what little of it remains today amounts to fragmentary traces rather than anything that might be read as a coherent structure.

The house was most likely built in the 18th century to replace Terryland Castle, which stood to the north and was burned in 1691, a casualty of the turbulent Williamite wars that reshaped land ownership and settlement across Connacht. The construction of a new house in place of a ruined or destroyed castle was a common enough pattern in post-war Ireland, as families sought to rebuild in a more domestic and less martial style. In this case, however, the replacement proved no more durable than what it replaced. The caretaker noted in 1838 was presumably maintaining a presence on the property rather than a habitable one, and the house continued its decline from that point until only the barest remnants survived.
