31, 33 West Port, Selkirk

31 and 33 West Port in Selkirk is a late 19th-century terraced tenement building, possibly incorporating earlier materials, with later additions and alterations. It stands two stories high with an attic and features three bays, including a shop on the ground floor. The first floor has painted render on the northwest elevation, accented with painted ashlar dressings, while the gablehead is finished with painted harl. The building includes a base course, a corbelled cornice above the fascia between the ground and first floor, and a mutuled course above the gablehead, just above eaves height, with quoin strips.

On the northwest elevation facing West Port, the building has a gabled design. The ground floor is arranged independently from the upper floor, featuring a two-leaf panelled door in the inner bay to the left, flanked by fixed pane plate glass shop windows. There is also a panelled door in the outer right bay, topped by a plate glass rectangular fanlight. Each bay on the first floor has a window, arranged regularly. The gablehead features half-timbering with two timber-mullioned tripartite windows and a rectangular panel above, adorned with green-glazed tiles.

The southeast elevation is not fully visible as of 1996, but it shows whinstone rubble at the first floor, with painted harl above the eaves height. There is a later adjoining single-storey addition at the rear, which is possibly made of red brick and has a piended roof.

The first floor has modern glazing, while the gablehead features timber windows with four-pane upper sections and plate glass lower sections for each light. The roof is covered with red tiles and has terracotta ridge tiles. There is a harled coped mutual stack on the southwest side, an ashlar coped stack on the gablehead to the northwest, and a harled coped wallhead stack on the southeast gable. The addition at the rear has a slate roof with strip skylights.

Inside, the building features a decorative scheme from around 1900. The front room has a compartmentalised ceiling with intricate plasterwork samples and ornate details above the picture rail. A timber glazed partition separates the rear of the front room, which has a segmental-arched opening in the centre. The boarded room at the rear, adjoining the addition, has iron trusses supporting the roof.
