Bus Garage Office, High Road, Port Bannatyne

The Bus Garage Office in Port Bannatyne is an early 20th-century building that stands two stories tall and features four bays, arranged in a 3-1 grouping. To the outer right, there is a single-bay hipped-gable wing that is recessed, and at the rear, there is a single-bay projection. The exterior is constructed of harl-pointed random rubble sandstone, with red sandstone ashlar dressings and red-brick at the rear that has polychrome dressings. The building has overhanging timber bracketed eaves and skewed gables above the first-floor windows. Notable architectural details include raised quoins, long and short surrounds to the openings, chamfered reveals, sandstone mullions, and segmental-arched openings at the rear.

On the northeast elevation facing High Road, the symmetrical three-bay wing to the left features a centrally located timber door at ground level, with an 8-pane fanlight above it and a segmental-arched surround. There is a bipartite window aligned with the door on the first floor. Flanking the entrance at ground level are bipartite windows, and there are tripartite windows centered beneath the gableheads that break the eaves on the first floor. The bay recessed to the outer right has bipartite windows on both floors.

The southwest elevation at the rear has a projecting bay at the center, which includes a two-leaf timber door at ground level and two small windows aligned on the first floor. There are single windows flanking the entrance at ground level, a single window at the first floor in the bay to the outer right, and two single windows at the first floor in the bay to the left. The recessed wing to the outer left features a single timber door at ground level.

The building predominantly has 6-pane upper and plate-glass lower timber sash and case glazing, along with some 6- and 8-pane timber casements. The roof is covered with red clay tiles, while the rear hipped-gable is finished with grey slates. The building has raised stone skews and replacement rainwater goods. There is a coursed sandstone ashlar stack to the northwest and a partial stack to the southeast.

The interior has been used as an office since 1997.
