It carries the deliberately cautious designation of "indeterminate date", a label used when a building cannot be confidently assigned to any particular century, whether because the physical remains are too fragmentary, the documentary record too sparse, or the architectural features too ambiguous to read clearly.

Killeen is a townland name derived from the Irish "cillín", typically referring to a small church or an informal burial ground, often one used historically for unbaptised infants or others excluded from consecrated ground. Whether that etymology has any bearing on the house recorded here is unknown, and the structural details, dimensions, and history of this particular building remain undocumented in publicly available sources at present.
