North Lighthouse Board, 84 George Street, Edinburgh

The North Lighthouse Board, located at 84 George Street in Edinburgh, was built by Claud Cleghorn between 1786 and 1788. It was reconstructed and unified by Rowand Anderson, Kininmonth & Paul from 1971 to 1973. Originally a three-storey building with a basement and attic, it features a seven-bay pair of houses with flats above, but is now used as a single office. The exterior is made of droved cream sandstone ashlar, which has been stone cleaned.

The center bay is slightly recessed, where a former common stair has been altered; the door has been replaced by a window at ground level. The three left bays have been reinstated as windows, while the three right bays are broader. The inner bay includes an Ionic columned doorpiece set within a segmental arch, featuring a modern timber radiating fanlight and a two-leaf panelled door. A model lighthouse is displayed at the first-floor window, and the building is topped with a mutuled eaves cornice and four matching pilastered tripartite box dormers. The rear elevation has been extended in modern style to the east, while the west retains original rubble with a full-height bow.

The interior includes an elegant timber porch that leads to a broad cross-vaulted Entrance Hall, which features an Ionic columned screen to the left that formerly led to the stair. The south wall displays a painting of a lighthouse, while the west wall has a plaster tableau. A double bow-ended room on the axis, which was the former Dining Room, has a fluted Ionic screen. The former Drawing Room at the front boasts a fine neo-classical carved and gesso chimneypiece, and a room to the southwest has been subdivided but retains a similar chimneypiece. The first and second floors are relatively plain, with the latter containing a former Dining Room of a flat to the southwest, featuring a fluted pilastered sideboard recess and another fine carved and gesso chimneypiece. The eastern section has good quality modern offices, including a brick and stone stair that encloses a lift.

Modern cast-iron railings are present around the property.
