The common is enclosed by distinct boundaries which generally are dictated by the topography. There are two distinct boundary types. The first is the wood-bank type, most frequent on the northern side, where an asymmetrical bank is topped by ancient beech trees outgrown from a former hedge. The banks today are being undermined by natural erosion of the sandy soil, especially where the tree roots have grown over. This is common along the edges of Spurfold, Ridings and Tenningshook Woods. On the common side is a ditch which in some cases has been enlarged to a hollow way by the passage of feet.
The second distinct boundary type is the rounded bank with a ditch. The latter is often silted up. Today, bank is topped by either a hedge or replaced by a wooden or wire fence depending on its location. Probably in the past there would have been a laid thorn hedge to prevent stock straying on to adjacent farmland. These banks can be found in varying degrees of preservation around the common, for example bounding the older properties which back on to the common at Felday and Pitland Street. At Mackie’s Hill, the common edge boundary forms the garden boundary whilst the “gardenification” of the drives lies within the common. The Tithe map clearly shows in many places that the roads which bound the eastern Hurtwood today were former tracks or routes running around the inside of the common boundary. Again, traces of the common boundary earthwork can often be seen forming the edge of gardens and fields on the opposite side of the road, for example around the southern edge of Holmbury Hill.
