Description

The National Westminster Bank is a single-storey building constructed from random squared rubble with ashlar dressings. It features a steep splay stone roof that is set back behind parapets, which rise at both gables to accommodate end wall stacks. The main block contains the banking hall, while the rear includes office spaces with a gabled wing to the east and a flat-roofed wing to the west.

The building has an angled corner entrance, which is accessed through a segmentally arched doorway topped with a mullioned leaded overlight. To the right of the doorway, there is an asymmetrical gabled return featuring a three-tier, three-light mullioned and transomed window, with an ashlar panel above that displays the name of the bank. The rear wing has a crow-stepped gable and parapet, along with a two-light mullioned and transomed window set back behind it.

The elevation facing the street includes a shallow canted six-light mullioned and transomed bay window towards the centre, flanked by single-light transomed windows. Above the central window, there is an ashlar recessed panel that also incorporates the name of the bank.

Inside, the banking hall is open to the roof, supported by collar strut trusses resting on stone corbels. The original fittings have been preserved, including simple 17th-century style panelling on the walls and counter, as well as a corner fireplace adorned with Delft tiles.
