The structure features a near symmetrical layout with a four-storey and attic block at the corner, showcasing Scottish 17th century architectural details.

The building is constructed from ashlar and bull-faced red sandstone, with ashlar dressings and polished granite columns. It includes a variety of window styles, such as ashlar transomed windows and mullioned and transomed windows, along with cill courses and an eaves course. The dormers are semi-circular and gable pedimented.

On the west elevation facing George Street, the building has a four-storey and attic canted angle at the corner, featuring regular windows and colonnettes at the angles that divide the bays on the second and third floors. The elevation is topped with a crenellated parapet and has pilastered dormers with semi-circular pedimented gables that cradle finials. The four-bay elevation onto Argyll Street includes a gabled bay off-centre to the right with canted oriels starting from the first floor.

A lop-sided gabled bay is located to the outer left, also featuring canted oriels from the first floor.

Most windows are timber sash and case, featuring various glazing patterns, including plate glass in the lower sashes, with 6-pane upper sashes, and 9-pane lower sashes with 6-pane upper sashes. The roof is covered with green slate, and there are tall corniced wallhead stacks, including a group of stacks that are diagonally set and linked with an oversailing cornice at the southwest angle and to the west.
