It has been identified as a house, which in archaeological terms can cover a considerable range, from the footprint of a medieval dwelling reduced to a grass-covered outline, to a post-medieval vernacular building whose walls still stand to some height. The date has been logged simply as indeterminate, which is itself a kind of information: whatever survives on the ground has not yet yielded enough evidence to place it confidently in any particular century.

Carrowmacloughlin is a small rural townland in Mayo, a county whose landscape holds an extraordinary density of archaeological remains, many of them poorly documented. The townland name follows the common Connacht pattern of Ceathrú, meaning a quarter division of land, combined with a personal or family name, in this case most likely derived from Mac Lochlainn. Such quarter-land divisions were a feature of the Gaelic land system and remained in use as administrative units long after the Gaelic order itself had collapsed. Within these small parcels of land, houses of many periods survive in various states, some known only from aerial photographs or fieldwalking, others simply noted in passing during broader surveys. This particular structure sits in that underdocumented category, recorded but not yet fully investigated or described in any publicly accessible form.
