89 Constitution Street, Leith, Edinburgh

89 Constitution Street is a two-storey office building designed in the style of James Simpson, dating from around 1890. It features a French classical style and includes a single-storey side wing to the north and a three-storey former warehouse at the rear, which has been converted into flats and offices. The building is constructed from cream sandstone with a polished ashlar front, although some plastic repairs are present. The rear and sides are made of squared and snecked stugged rubble.

The front elevation has three bays with single windows at the ground floor. The first floor features a tripartite keystoned window that is slightly corbelled and bowed in the center, flanked by single windows with lugged architraves. To the left, there is a two-bay single-storey wing that includes a doorway with a panelled door and a rectangular plate glass fanlight to the right, and a recessed bowed tripartite window to the left with a panelled apron and channelled jambs. The wallhead of the warehouse behind has two shouldered and slightly projecting wallhead stacks.

On the southwest elevation, the first floor of the left bay is finished in polished ashlar and has a bipartite window. There is also a tall round-arched stair window with a thin timber mullion, along with two bipartite windows at the ground floor, irregular single windows, and a small wallhead stack.

The northeast elevation features a single-storey side wing at the ground floor, with an ashlar first floor above that has a bipartite window. The warehouse block includes a single window and a fire escape stair at the second floor, while the rear portion of this elevation is obscured by a neighbouring building.

The southeast elevation is three-storey, partly rendered, and has three windows in the central bays, with a slightly projecting wallhead stack to the left and a bipartite wallhead dormer to the right.

The windows throughout are plate glass timber sash and case. The building has a black slate piend and platform roof with lead flashings on the warehouse, and there are four wallhead stacks. The interior was not seen in 1993.
