Manager's Drawing Office, Great North Of Scotland Locomotive Works, Harlaw Road, Inverurie

The Manager's Drawing Office at the Great North of Scotland Locomotive Works in Inverurie was designed by William Pickersgill between 1902 and 1905. This rectangular building features two storeys, a basement at the rear, and an attic, situated on a sloping site. It is a large structure with modern additions and linking sections at the rear that are not included in the listing. The design incorporates a mix of classical and other detailing, including projecting skews and skewputts. The building is primarily constructed of squared, coursed granite rubble with ashlar dressings. Notable architectural elements include a base course, a first-floor cill course, a double eaves band, and an eaves cornice, with predominantly regular fenestration.

On the southwest elevation, there is a four-bay facade featuring a projecting flat-roofed single-storey entrance hall at the centre. The ground floor of this section has a timber-panelled door with narrow margin lights set within an opening that has a shaped lintel. Above this, there is an open-topped pediment flanked by finialled consoles, breaking the eaves cornice. The attic floor displays a gable on the left and a long pilastered dormer on the right.

The northwest elevation consists of six bays, with a corbel table located beneath the eaves band on the right side. The northeast elevation has three bays, featuring a full-height canted bay window on the left, with projecting link sections to an extension at the ground and first floors, and a gable on the right side of the roof. The southeast elevation is characterized by an M-gabled design.

The glazing throughout the building predominantly consists of single-pane windows in timber sash and case style, along with several rooflights.
