Description
15 The Cathedral Green is a two-storey, two-bay house, likely dating from the late 17th or early 18th century, with later alterations. The front facade is rendered and has a plain Welsh slate roof. The ground floor features two six-over-six sash windows, dating from around 1980, to the left. A round-headed doorway, containing a six-panel door with raised-and-fielded panels and a plain fanlight, is positioned to the right. Above, the first floor has two six-over-six sash windows, with a late 20th-century rooflight situated above. A brick stack is visible on the left gable. The rear elevation was not visible during the resurvey. The interior was not inspected.
