30 High Street, Kirkwall

30 High Street in Kirkwall is an 18th-century house that has undergone alterations and additions. It is a two-storey, three-bay, near-symmetrical rectangular building, featuring a modern single-storey piended addition on the southwest (principal) elevation, which is not in keeping with the original style. There is also a single-storey, two-bay lean-to garage addition on the outer right and a two-bay gabled end facing the street, built on ground that rises to the southwest. The exterior is harled.

On the southwest elevation, there is a large window in the centre of the modern addition, with a window on the left return and a glazed modern door on the right return. Each bay has a window on both floors flanking the central area. The outer right addition features a modern tilting garage door with a window to the left.

The northeast elevation, which faces High Street, has a window in the right bay on both floors and a ground floor window in the left bay. There is a gablehead stack present.

The windows are primarily 2-pane timber sash and case, with a modern timber-framed window in the piended addition and a centred rooflight on the southwest pitch. The roof is covered with modern grey slate and has a red clay ridge. The gablehead stacks on the northeast and southwest are corniced and harled, and the property has uPVC rainwater goods.

The interior was not seen during the last inspection in 1998. The boundary walls consist of a low, harled coped wall along the southwest boundary, with square plan gatepiers at each end.
