Sule Skerry Lighthouse Station, 15 Ness Road, Stromness

Sule Skerry Lighthouse Station, built in 1892 with later alterations, is a former lighthouse shore station located at 15 Ness Road in Stromness. This two-storey, seven-bay building has a rectangular plan and is symmetrical in design, featuring single-storey flat-roofed wings on either side. The structure is set on raised ground and is finished with painted harl. Architectural details include a base course, a cill course for the first-floor windows, an eaves course, and a modillioned cornice, along with painted long and short ashlar margins and quoins.

The principal elevation features a grouping of bays in a 1-5-1 arrangement. It has a pitch-roofed porch with a finial and a round arch to the gablet, supported by square columns at the ground level in the central bay. The porch has two-leaf part-glazed boarded doors, a date inscribed on the lintel, and a carved and painted lighthouse scene below the round arch. Above, there is a window at the first floor, flanked by two wallhead stacks. Each of the flanking bays has a window at both floors, and there are boarded doors in each of the wings.

On the south side elevation, there are two windows set closely together in the centre of the advanced single-storey wing, with a window between the gables at the first floor and gablehead stacks above each gable. The north side elevation features a window in the centre of the wing at ground level and another window between the gables at the first floor, also with gablehead stacks above.

The building has 4-pane timber sash and case windows, although some have been replaced with uPVC glazing. The roof is covered with grey slate and has a red clay ridge, with coped ashlar stacks and decorative cast-iron rainwater goods.

The interior was not seen in 1997. The boundary walls consist of harl-pointed rubble with a ridged ashlar cope, and there are stop-chamfered square-plan ashlar sandstone piers topped with trefoil-incised round-arched caps.
