12-18 West Port, Selkirk

12-18 West Port in Selkirk is a later 19th-century, two-storey, three-bay terraced tenement with a shop on the ground floor. The building is constructed from squared and snecked whinstone, which is painted at the ground level, and features droved and polished ashlar sandstone dressings. It has a base course, a band course between the ground and first floor, and a raised cornice above the fascia, along with an eaves course.

On the southeast elevation, the windows are regularly arranged on the first floor. There are two two-leaf panelled doors at the center, each with a plate glass letterbox fanlight above. A window is located in each flanking bay, and there is a fascia that spans the doors and flanking windows. To the outer right, there is a panelled tenement door with a plate glass letterbox fanlight above.

The northwest elevation was not seen in 1995. The first-floor windows are plate glass timber sash and case, while the ground floor features plate glass fixed-pane windows. The roof is slate, with a modern slate-hung box dormer that spans almost the entire length of the building. There are ashlar coped mutual stacks at the northeast and southwest. The interior was not seen in 1995.
