6 Nicolson Street, Kirkwall

6 Nicolson Street in Kirkwall is a later 18th-century house that has undergone some alterations. It is a two-storey, three-bay rectangular building with a plain symmetrical design and crow-stepped gables. The entrance features a gabled porch with a ball finial at the center, and there is a lean-to projection at the rear. The exterior is harled.

On the southwest, or principal elevation, there is a window in the entrance porch at ground level, a modern part-glazed door to the left, and a window above on the first floor. Each of the flanking bays has a window on both floors. The southeast and northwest side elevations are blank. The northeast rear elevation includes the lean-to projection that spans the ground floor bays.

The house features 12-pane timber sash and case windows, with a fixed timber-framed window in the porch. The roof is traditionally covered with graded Caithness stone tiles and has a stone ridge. There are harled, corniced stacks on the southeast and northwest sides, with polygonal cans, and uPVC rainwater goods.

The interior was not seen during the last inspection in 1998. The boundary walls consist of low harled walls with an ashlar coping that runs along the front elevation from the porch.
