What survives at Brackaharagh is the foundation course of a small rectangular house, measuring roughly six metres by five metres internally, with walls about 1.3 metres wide. It is not grand, and it was probably never intended to be. What makes it quietly arresting is precisely that anonymity: no date can be assigned to it, no builder named, no historical event attached.

The construction technique offers some detail, even if the broader context remains out of reach. The inner face of the foundations is formed by flat slabs set upright on their edges, each averaging around 75 centimetres long, creating a neat revetment against whatever fill packed the wall core. The outer face, where it can still be made out beneath the overgrowth, shows rougher coursed masonry. At the southern side, the original entrance survives, marked by two upright slabs placed 80 centimetres apart, wide enough for a single person to pass through comfortably. A later field wall cuts straight across the interior, bisecting the building entirely, and the eastern half of the floor area is now choked with stone debris. The wall is a reminder that this ground has continued to be worked and divided long after the house fell out of use, its ruins absorbed into the agricultural landscape without ceremony. The survey of the Iveragh Peninsula compiled by A. O'Sullivan and J. Sheehan, published by Cork University Press in 1996, recorded the structure without being able to pin down when it was built or abandoned.
