Description

The boundary walls and slate fencing for Nos. 24 and 25 are made of low, uncoursed rubblestone. These walls are located on the opposite side of the road from the cottages, although the wall for No. 25 is missing. The walls connect with slate fencing, which consists of thin vertical slate slabs set into the ground and linked by horizontal wire, including along the common boundary. At the rear of the cottages, the boundaries are also slate fenced on the sides and back. The back fence is part of a long slate fence that defines the rear boundary for all the plots of cottages along Tan y Bwlch. The front plots extend approximately 100 meters from the road, while the rear plots extend about 60 meters.
