Description

No. 20 Heathfield Terrace is a stucco-fronted house with a Welsh slate roof, dating from the 18th century. It is a two-window-wide building of three storeys and a basement. A decorative band separates the ground and middle floors. The windows have flat arches and glazing bars. A patera embellishes the corner of the reed cornice. The entrance features a five-panel door protected by an attractive glazed, semi-circular fanlight. To the side is a lower wing, two storeys high, slightly set back from the main facade and containing one window on each storey.
