The structure, roughly 7.5 metres long and just 15 centimetres thick, consists of small-diameter branches laid in a north-south orientation, visible in both walls of the drainage cut. No tool marks or shaped timber were found, which makes it difficult to date with precision or assign to a particular tradition of woodworking.

Archaeologists interpret it as the remains of a peatland platform, a type of structure known from Irish bogs in which brushwood, planks, or other organic material was laid across wet or waterlogged ground, perhaps to create a stable surface for walking, working, or storing goods at the bog's edge. The site was originally catalogued as two separate monuments, references 27A and 28A, before closer examination suggested both entries described the same deposit. Without woodworking evidence to study, the precise date of the platform remains uncertain, though the preservation of organic material in peat can be remarkable, with some such structures surviving for thousands of years in conditions that would destroy them entirely on dry land.
