Nineteen such platforms were identified during field survey of the bog, each one a deliberate intervention in a landscape that would have been actively hostile to construction. That so many survive, and in enough detail to reveal their carpentry, speaks to how effectively bog conditions prevent the decay of organic material.

The platforms were built primarily from brushwood and roundwood, the basic vocabulary of timber construction before sawn planks became common. In several cases, builders went further: three platforms used small anchoring pegs to hold the structure in place, and two examples showed woven brushwood, a technique that adds lateral strength by interlacing flexible stems. Wood species identified across nine of the sites included alder, ash, birch, hazel, and willow, all trees that would have grown at the bog's margins and been readily available. Radiocarbon dating of four platforms produced a spread running from the Late Bronze Age, somewhere between 792 and 526 BC, through to the Iron Age, with one platform dated to between 351 and 120 BC. Whether these were walkways, fishing stations, places to process material at the water's edge, or something else entirely, the record does not say with certainty, but the consistency of the construction methods across multiple sites suggests a practised, repeated tradition rather than improvised one-off building.
