170, 172, 174 Constitution Street in Edinburgh is a four-storey corner tenement building designed by A Thomson in 1882, featuring classical detailing. The building is constructed of cream sandstone with polished ashlar on the main elevations, while the rear and side are made of squared and snecked stugged rubble. Architectural features include a band course above the ground floor, a cill band course at the second floor, an eaves cornice, and a blocking course. The ground floor has roll-moulded segmental-arched windows, while the first and second floors have architraved windows with bracketed cills, except for the first-floor windows on the southwest side, which are corniced with an oval astragal pattern. The building also has rusticated quoins.

On the southwest elevation facing Duke Street, there are four bays, including a rounded corner bay on the outer right. The ground floor has a modern shopfront, and the corner bay is slightly recessed, framed by rusticated quoins. The first-floor window in this bay features a consoled pediment, while the second-floor window is corniced. The third floor has single windows, and there are two short wallhead stacks. The bay to the right of the center and the outer left have single windows, while the bay to the left of the center has a two-storey canted window at the first and second floors, with a tripartite window at the third floor.

The southeast elevation facing Constitution Street has nine bays. The ground floor features small paired windows, some of which are blocked, along with three secondary doorways. The first, fourth, fifth, and eighth bays from the left have bipartite windows, with the first-floor windows pedimented and the second-floor windows featuring architraves circled over the mullion. The remaining bays have single windows, and there are three short shouldered wallhead stacks.

The northeast elevation is gabled and includes a later brick-built stair tower and additional structures. The northwest (rear) elevation has irregular single windows and later brick-built additions.

The building features timber sash and case windows, mostly with plate glass glazing, and the first-floor windows have a distinctive oval astragal pattern. The slate roof is fitted with lead flashings and has five wallhead stacks. Ornamental gutter heads are also present. The interior was not seen in 1993.
