No further detail has been attached to it, at least not in any publicly accessible form. It sits in the archaeological record as a kind of placeholder, acknowledged but not yet explained, which is itself a quietly interesting condition for a building to be in.

Sheeaun is a small rural townland in Clare, a county whose landscape is layered with settlement evidence ranging from prehistoric to post-medieval. The designation "house of indeterminate date" is not unusual in Irish archaeological survey work. It typically means the structure has been identified and logged, perhaps as a roofless ruin, a set of collapsed walls, or a clearly domestic footprint visible on the ground or from aerial survey, but that not enough survives, and no documentary record has yet been found, to assign it confidently to a period. It could be a post-medieval vernacular dwelling, the remnant of a farm cleared during or after the Famine, or something considerably older. The indeterminacy is honest rather than evasive.
