National Westminster Bank

The National Westminster Bank is a bank building that stands three storeys high with an attic. The elevation facing Lloyd Street features six windows, while the Mostyn Street elevation has two. The building is topped with a hipped slate roof that includes box dormers. Its walls are faced with Portland Stone ashlar, and the upper floors have small-pane sash glazing. A crowning modillion cornice and blocking course are present, along with quoins.

On the Lloyd Street elevation, the windows are closely spaced, with a large blank area at each end. The second-floor windows have moulded architraves and plain aprons that extend down to the top of the first-floor cornices. The first-floor windows are taller, also featuring moulded architraves and cornices supported by consoles, with turned balusters at sill level. There is a cornice at the first-floor level. The ground floor is rusticated below the impost level of the windows, which are set within three tall, wide, round-headed arches that have moulded archivolts and keystones.

The Mostyn Street elevation includes two tall box dormers and a triangular pediment with modillions above the second floor. The first-floor windows here also have moulded architraves, pulvinated friezes, and cornices on consoles. The ground floor features a recessed semi-circular headed porch in a tall projecting wing, which has a balustraded parapet and four tall urns. The porch is flanked by flat-headed niches on either side.

Inside, the ground floor banking hall displays simple classical detailing on the walls and ceiling.
