11 Union Place, Montrose

9 Union Place in Montrose is a terrace of four houses built in the earlier 19th century. Each house is two stories high, with an attic and basement, and they are arranged in mirrored pairs. The front is made of sandstone ashlar, while the sides are harled and the rear is constructed from squared rubble. The design includes a band course below and above the ground floor, an eaves cornice, and a blocking course, along with raised margins and quoins.

The principal elevation features No 8 on the right, which has a bipartite window and a single window in the basement. A six-step stone flight with cast-iron railings leads to the entrance at the raised ground floor, which has a round-arch with a recessed, pilastered doorway and decorative glazing bars in the fanlight above a six-panel door. To the right, there are two architraved windows with panelled aprons. Above, three windows are centered on the first floor. A bowed, three-light dormer is offset to the right. No 9 on the left is a mirror image of No 8 but has a single window in the basement that is blocked. No 10 mirrors No 8 but has a door to the left in the basement. No 11 is also a mirror image of No 8.

The north and south elevations are blank gable ends. The east elevation features a two-bay rear with a small piended dormer for each house. Nos 8 and 9 have 12-pane timber sash and case windows, while Nos 10 and 11 have plate glass windows. The roof is covered with grey slate and has coped skews. There are rendered gablehead stacks on the north and south sides, a ridge stack at the center, and a shouldered ashlar wallhead stack to the left at the rear.

The interior was not seen in 1998. The boundary walls consist of a low, coped ashlar wall at the front, with later steel railings for Nos 8 and 9, and rubble boundary walls at the rear.
