The exposed width measured 4.5 metres, with a depth of up to 0.3 metres, and the structure consisted of two or three roundwoods, the untrimmed trunks or branches used as the main load-bearing elements, packed with smaller pieces of brushwood and loose twigs to fill the gaps. One of those roundwoods showed what may have been a worked end, a possible sign that the timber had been shaped or prepared rather than simply gathered and laid.

Corlea is already known as a place of exceptional bogland archaeology. Peatland platforms of this kind were typically built to provide a stable surface over soft or flooded terrain, functioning somewhere between a trackway and a foundation. They vary enormously in age and purpose, from Bronze Age and Iron Age examples to early medieval structures, and the bog preserves organic material that would long since have rotted away in open air. Beneath this particular platform, excavation recorded concentrations of natural wood and roots, suggesting the structure was laid directly over existing vegetation rather than onto bare peat. The work was recorded by Dunne in 1999, under reference 99LBW0007A.
