21 Lewis Street, Stranraer

21 Lewis Street in Stranraer is a mid-19th century, two-storey terraced house with an attic, designed in a symmetrical T-plan layout. The exterior features painted render, a base course, and architraves around the openings.

On the southwest entrance elevation, there is a step leading to the central entrance, which is highlighted by a consoled corniced doorpiece. The entrance includes a six-panelled timber door with a fanlight above it. There is a single window above the entrance on the first floor, along with single windows on both floors of the flanking bays. At the attic level, there are three corniced dormers.

The ground floor windows are fitted with plate glass, while the upper storey features 12-pane timber sash and case windows. The roof is covered with grey slate and includes stone skews, a rubble ridge stack on the left, and a rendered ridge stack on the right that is shared with adjacent properties. The house also has corniced cans.

The interior was not seen in 1997.

The property is enclosed by a rendered coped boundary wall, with square-plan panelled gatepiers flanking the central pedestrian entrance and an entrance to a pend on the outer right. The gatepiers have tapered moulded caps, and there is a cast-iron gate along with cast-iron railings.
