31, 33 Bridge Street, Montrose

31 and 33 Bridge Street is a large, mid-19th century, three-storey and attic, two-bay L-plan house that once housed a shop on the ground floor. The building is constructed of sandstone, featuring ashlar stonework on the front and squared rubble on the sides and rear. It has a base course, a frieze, and a cornice above the ground floor, along with a cill band course on the second floor, an eaves cornice, pilaster ends, and architraved margins.

The west elevation, which is the principal facade, has a four-bay arcaded ground floor that has been altered at the center. The bays are defined by three attached Roman Doric columns and panelled pilaster ends, all decorated with banded detailing and fluted consoles above the capitals. The two central bays are partly filled with modern windows, while the bay to the right features two-leaf panelled doors, and the bay to the left has a four-panel door with a rectangular fanlight. On the first floor, there are canted bay windows to the right with Doric columnar mullions and a corniced head, and a window to the left also with a corniced head. The second floor has a stone-mullioned bipartite window to the right and a single window to the left, along with two small modern dormers above.

The south elevation is a gable end with a window to the right on the first floor. The north elevation is also a gable end, featuring a door and window to the left at ground level. There is a small two-storey, flat-roofed wing to the left (rear) that includes two windows and a door at ground level, two windows on the first floor, and a carved figure of a mother with a baby and infant in a niche on a corbelled base to the right.

The building has timber sash and case windows with plate glass. The roof is pitched with grey slate, and it features stone skews and skewputts. There are gablehead stacks made of polychromatic brick with bands and cornices, with the northern stack being broad and having a full complement of square section cans.

The interior was not seen in 1998.
