Lodge, Grammar School, Skene Street, Aberdeen

The lodge, likely designed by James Matthews around 1860, stands to the southeast of Aberdeen Grammar School. It is a single-story building with a basement, featuring four bays. The exterior is constructed of finely finished, tooled coursed granite ashlar with detailed margins. Key features include a projecting base course, chamfered window reveals, curved corner angles corbelled to right angles below the eaves, an eaves course, crowstepped gables with inset blind openings, and spherical finials at the apex.

The northeast (entrance) elevation is asymmetrical, with a gabled porch advanced towards the penultimate bay on the left. A segmental-arched doorway is adorned with decorative roll moulding and a keystone, leading to a timber door, with a small window to the right return. A window is situated in the outer left bay, and further windows are present in the penultimate and outer right bays.

The northwest elevation, also asymmetrical and two-bayed, features a gabled bay to the left and an advanced gabled bay to the right, with irregular fenestration to the basement. A single window is positioned off-centre to the left of the ground floor.

The southwest elevation displays a gabled bay to the right, with the remainder of the elevation not visible in 2000. The southeast elevation, asymmetrical and two-bayed, features an advanced gabled bay to the right along with a canted window with a stone piended roof on the ground floor, and a window to the recessed bay to the left.

The lodge has a variety of small-pane timber sash and case windows. A grey slate roof with lead ridges is complemented by beaked skewputts. Coped granite gablehead and ridge stacks are topped with circular cans, and cast-iron rainwater goods are present. The interior was not inspected in 2000.

A bridge over Den Burn, along with gates, gate piers, boundary walls, and railings, are also part of the listing. Looped iron railings with decorative iron piers form the parapet of the bridge over Den Burn to the northeast of the lodge. Four square-plan granite gate piers mark the main entrance to the southeast of the lodge; these have rough-faced exteriors, finely finished margins, stop-chamfered angles, cornices, and pyramidal caps surmounted by spherical finials. A two-leaf decorative iron gate sits at the centre, flanked by two pedestrian gates on either side. Low granite walls extend to the left and right, sweeping outwards to the street and topped with decorative iron railings featuring fleur-de-lys caps. Piers are situated at the angles. Two piers are also found to the north of the gates, within a playground. A granite wall runs along the east side, coped and topped with decorative iron railings with foliate caps, featuring a two-leaf iron gate at the centre with decorative iron piers, and stone steps leading up to the playground level. Rubble walls extend to the remainder, with pointed coping and simple iron gates set within square-plan gatepiers.
