Gatepiers and boundary walls at County Buildings, Breadalbane Street, Tobermory

The County Buildings, formerly a court house and prison, were designed by John Dick Peddie and Charles Kinnear in 1862. This two-storey, three-bay building features a rectangular plan and is styled in the Scots Baronial manner. It is situated on elevated ground that overlooks Tobermory Harbour. The structure is constructed from squared and snecked rubble with ashlar dressings, chamfered reveals, and crowstepped gables. The corners are curved and corbelled out at the first floor, while the entrance bay on the north side is advanced and crowned with a crowstep gable, featuring a segmental arched doorway at its center. The building has shouldered chimney stacks at the corners, and the side elevations display gabled outer bays with wallhead chimney stacks. The former courtroom on the first floor is adorned with three gableted windows topped with thistle finials, while the ground floor east elevation has four horizontal, small-pane glazed openings for the former cells.

The windows are primarily timber sash and case with a six-pane glazing pattern, and the roof is covered with grey slate and features coped wallhead stacks.

The interior has not been accessed, but photographs of the former courtroom, which is now used as a registry office, reveal timber panelling up to dado height and a segmental-arched recess in the south wall behind a raised timber judge's bench, which has a later pieced fretwork frieze. To the left of this recess, there is a raised cast iron fireplace.

In front of the building on Breadalbane Street, there are three sandstone ashlar gatepiers that are square in plan and coped, including a pedestrian entrance. The boundary wall is made of rubble with rubble copes and features a curving section of retaining wall to the north.
