2 Commercial Street, excluding 20th century extensions to rear, Port William

This late 18th century building, formerly an inn, was raised to two storeys after the mid-19th century. The listing excludes the single-storey 20th century extensions and the late 19th century detached outbuilding at the rear.

The building has a roughly rectangular plan with three wide bays, or four bays at ground level, featuring asymmetrically arranged openings. It is rendered, with coursed rubble at the ground level and brick at the first floor, and has painted margins around the doors and windows. The ground floor has smaller windows of varying sizes, while the first floor features windows with projecting cills.

On the principal (north) elevation, there is a two-leaf timber panelled door to the left of centre, accompanied by a fanlight and a semicircular panel above the door, likely from the early 20th century.

The east elevation has a gabled section to the right with an adjoining timber gate and a first-floor window to the left. The west elevation features an offset chimney breast and a rendered brick wall to the left. The rear (south) elevation includes a full-height gabled jamb to the right and a single-storey gabled jamb at the centre, both of which are fronted by lean-to additions from the early and late 20th century.

The building predominantly has 12-pane glazing in timber sash and case windows throughout. It features red sandstone coped skews and a slated roof with rendered gablehead chimneystacks on the east, west, and south sides, along with ridge chimneystacks to the west of the centre of the main roof, all topped with octagonal cans.

The interior, observed in 2015, retains some 19th century details, including a tiled floor in the entrance vestibule, a decorative painted iron balustrade with a timber handrail on the stair, moulded timber architraves, and some window shutters.
