16, 18 High Street, Selkirk

16 and 18 High Street in Selkirk is an earlier 19th-century two-storey, three-bay tenement with a shop on the ground floor. The building features squared and snecked whinstone with polished ashlar margins, and droved ashlar tails to the first-floor windows. The ground floor is made of whinstone rubble, while the first floor has harling on the southeast and southwest elevations, and the northeast elevation is fully harled with ashlar cills. The building has quoin strips with flush long and short droved ashlar quoins, and stop-chamfered arrises to the door openings at the ground level.

On the northwest (High Street) elevation, there is a deep-set partly-glazed shop door to the right of the centre, and a partly-glazed door with a plate glass rectangular fanlight above to the left of the centre. Both doors are flanked by large plate glass windows, which are part of a later 19th-century shop front in the bay to the right. There is a window in each bay on the first floor, and evidence of a former uniting corniced shop fascia.

The southeast elevation features a full-height projection from the bay on the left, with a further projection to the northeast. The building has a variety of windows, including modern plate glass swinging windows on the northwest at the first floor, plate glass fixed-pane windows at the ground, and plate glass alongside 12-pane timber sash and case windows. The roof is slate with ashlar coped skews and skewputts, and there are ashlar coped wallhead stacks on the side elevations. The interior was not seen in 1996.
