It has been logged as a house, but the date assigned to it is simply "indeterminate", a designation that, in archaeological terms, means the evidence on the ground has not yet yielded enough to place it confidently within any particular century or era. That kind of ambiguity is not uncommon in rural Ireland, where the remains of vernacular buildings, field houses, and seasonal shelters can be extraordinarily difficult to date without excavation or documentary support.

Furroor sits within a county that has been continuously settled for millennia, from the megalithic tombs of the Burren to the post-medieval farmsteads that dot its quieter inland stretches. A structure recorded simply as a house, without further qualification, could belong to almost any period from the early medieval to the nineteenth century. The absence of a date is itself a kind of information, suggesting that surface remains are ambiguous, that no associated finds or historical records have pinned it down, or simply that detailed survey work in this particular corner of Clare has not yet been completed. Many such structures across Ireland are the remnants of homes abandoned during or after the Great Famine, though others prove, on closer inspection, to be considerably older.
