40 Dundas Street, Stromness

40 Dundas Street in Stromness is a house dating from the late 18th to early 19th century. It is a two-storey structure with an attic and basement, featuring a symmetrical three-bay rectangular plan and a crow-stepped gable facing the sea to the east. The exterior is made of harled-pointed roughly coursed random rubble with cement margins around the openings, while the east side is fully harled.

On the south elevation, which is the principal front, there is a deep-set modern part-glazed timber door with a three-light rectangular fanlight located in the central bay, with a window above it on the first floor. Each of the three bays has a window on both the ground and first floors, as well as in the attic.

The east elevation, which faces the sea, features a single bay gabled wall. It has a boarded door at the basement level, a window at ground level, and a small attic window positioned to the left of centre. Above this is a multi-flue gablehead stack.

The windows have modern glazing with top-hung upper lights, and the attic windows are fixed timber-framed. The roof is covered with Caithness slate and has a stone ridge, with harled stacks on both the east and west sides and moulded cans. The rainwater goods are made of uPVC.

The interior was not seen during the inspection in 1997. There is also a walled garden to the east, enclosed by open-jointed Caithness flagstone walls alongside random rubble walls, creating a rectangular-plan garden.
