1. The former church of St John is located on the south side of Tranch Road opposite its junction with Penywain Lane. The church was present in the later nineteenth century when it appears on the first and second edition Ordnance Survey maps of the area. By the third edition (1920) it was portrayed instead as 'Church Hall'. Presumably this was the forerunner of the Church of St John the Evangelist, located a short distance away at the north end of Penywain Lane, and which was built in 1912 (NPRN 12954).
The original church is now the Waunfelin and Pen Tranch Community Hall. It is constructed of stone rubble with dressed quoins under a corrugated-iron roof. It is a rectangular building with a lean-to porch on the west gable, of similar construction but with red brick dressings around the arched doorway, and a short flat-roofed projection - of one build with the main structure - on the east gable. Windows are rectangular including those in the nave which appear to have been converted from simple arched windows.

2. St John's church was originally located on the south side of Tranch Road, opposite its junction with Penywain Lane. It appears on the Ordnance Survey first-edition map of 1881. The church relocated to a new site about 0.5km to the north in 1912-13 (NPRN 12954). The former church became the church hall, as portrayed on the 1920 map, and is now the Wainfelin and Pen Tranch Community Hall.
The building is constructed of roughly-coursed sandstone rubble with red brick dressings to the entrance, and corrugated iron (?) roofs. Its plan is much as portrayed in 1880. It is a simple rectangular structure, long axis aligned east by west, with lean-to porch on the west end-wall (north-facing entrance) and a short flat-roofed extension on the east end-wall. Windows, originally with pointed arches, have been modernised as rectangular openings, the arched areas infilled with brick. A second entrance is located on the north wall towards its east end, approached by a ramp alongside the building. Additional window openings have also been added.
