The Puzzle Tree Restaurant, including Stone Wall and Railings

The Puzzle Tree Restaurant, originally a bank, is a two-storey building with a cellar, featuring stucco on a grey rusticated stone plinth. It has two wings with slate hipped roofs positioned at right angles to each other, and a convex bay located between the return elevations at the corner. There is a band at the first-floor sill level, and the building generally has 12-pane sash windows.

The elevation facing The Watton consists of two bays, with first-floor window openings adorned with moulded architraves, while the ground-floor window openings feature friezes, cornices, and panelled aprons. The elevation towards Danygaer Road has three bays, where the ground-floor windows in the end bays are tripartite sash windows, separated by stuccoed pilasters between the lights, and topped with cornices and triangular pediments over the centre light. The centre window also has a frieze and cornice above it.

The convex corner bay is recessed, with a doorway situated behind a convex Roman Doric porch. The Watton elevation is set back behind a small enclosure, which is bordered by a stone wall and iron railings that extend to No. 37 The Watton. Inside, the restaurant features a small octagonal vestibule with a moulded cornice.
