19A Dundas Street, Stromness

19A Dundas Street in Stromness is a mid-19th century house with later alterations. It is a two-storey building with an attic and has a rectangular plan that is asymmetrical, featuring five bays on the upper floor and seven bays on the ground floor. The house incorporates a three-bay shop on the right side, which forms a terrace with a fenestrated chamfered bay at the outer right. The ground floor is painted cement-rendered and lined, while the first floor is made of roughly coursed rubble with harl-pointed finish and cement margins around the windows. The south side is harled, and there is a band course between the ground and first floors.

On the east (principal) elevation, the bays are grouped four to the left and three to the right on the ground floor. The four-bay group on the left has two deep-set timber doors with fanlights located to the right of the centre, with a window in each of the left bays. The three-bay shop group on the right features a modern part-glazed timber door in the centre bay, with a window flanking each side. The first floor has irregular fenestration, including a gabletted dormer that breaks the eaves in the outer left bay and a small attic window in the chamfered bay on the outer right.

The south side elevation has a single bay gabled section with an attic window at the gablehead. The building predominantly features 12-pane timber sash and case windows, picture windows in the shop, and fixed small-pane timber-framed windows at the ground level to the left. The roof is covered with grey slate, has a red clay ridge, and slate on the dormer. There is a harled coped common stack on the north side and uPVC rainwater goods.
