In the early 1980s several huts and a water tower were also visible on the now Waltwood Park Drive area, this area belonged to the General Post Office and was used to house old telecommunications equipment until it was sold and demolished by British Telecom who took over the site when the organisation was privatised in the early 1980s.

The Underwood Estate is situated in a natural land formation within the falls of a wooded area on the south and north side and a small drainage ditch or reen called "Monks Ditch" on the northern side of the development.

The Leisure Centre was closed and sold in 2013 to cut costs; the following year the police discovered it was one of the largest cannabis factories in Gwent, housing an estimated 4000 plants with a value of £1.1 million.

Within St. Martin's Church is the great stone tomb of Sir Nicolas Morgan, the Knight of Pencoed Castle in the reign of Henry VII.
