25 Bridge Street, Montrose

25 Bridge Street in Montrose is an early 19th-century, two-storey house with an attic and basement, featuring five bays in a classical style. The front is constructed from stugged sandstone ashlar, while the rear is made of rubble and rendered on the sides. The building has a rubble stone foundation, a basement cill course, a band course above the basement, a ground floor cill course, an eaves band course, a cornice, and a blocking course, all with chamfered margins and rusticated quoins.

The west elevation is symmetrical, with an eight-step flight and platform leading to a central doorpiece supported by slender Doric columns and topped with an entablature. The entrance features a four-panel door and a rectangular fanlight, with a window centered above it on the first floor. There are two bays on either side with windows on both the ground and first floors, along with one semicircular basement window and one canted dormer on each side between the outer bays.

The north elevation is a blank gable end, while the south elevation has a gable end adjoining another building at the ground floor. The east elevation consists of three bays, with a bowed stair tower in the center that has a door at the ground level and a tall window above. The flanking bays feature windows on both the ground and first floors, with the right ground floor window blocked.

The first-floor windows on the front are 12-pane timber sash and case, while the ground floor has plate glass. The basement windows feature radial and geometric glazing. The rear has 12-pane windows on the first floor, with four-pane and plate glass windows elsewhere. The roof is pitched with grey slate, coped skews, and skewputts, and decorative wrought-iron finials adorn the dormers and stair tower. Brick stacks are located at the gable heads.

The interior was not seen in 1998. The property is surrounded by coped rubble boundary walls at the front, which include square-section rusticated gatepiers and a timber gate. There is a partial brick wall to the southwest, a brick wall to the north at the rear, and a raised ashlar wall to the east with timber gates. Wrought-iron railings front the basement.
