The barn at Treban farm has characteristic elements of an early post-medieval agricultural building for keeping sheep or cattle although some elements of the earlier phase of this building including the few in situ and reused timbers might point to a slightly earlier, later medieval date. The original layout and features survive to inform the nature and function of the building as a livestock farm building, with stalls on the ground floor and storage as a hayloft above.

The ranges of the building are constructed from irregular rough stones with larger angular stones at corners and the base of the walls. The stone is bonded with sandy lime mortar. The buildings have been subject to later additions of cement render and in places in-fill with modern breeze-blocks, with a slate roof heavily patched with tar. 

The buildings fit into the local rural and industrial economy of the region of the early post-medieval period or perhaps earlier, and due to its rarity is certainly of regional significance.
