Garden Wall, Privy and Gatepiers of Oak Cottage

The garden wall, privy, and gatepiers of Oak Cottage are notable features from the 19th century. The square brick gate piers have peaked capping and support a 19th-century iron gate at the top of a flight of steps that leads down to a rear entry. To the north-west of the house, there is an iron post that was used in connection with Melingriffith lock on the Glamorganshire Canal, which was closed in 1942. Additionally, a wall encloses the garden to the south of the house, made of colourwashed stone rubble with rough capping. This wall includes a privy and outhouse located in the south-west corner, which has a roof made of corrugated steel sheeting.
