124 Great Junction Street, Edinburgh

124 Great Junction Street in Edinburgh is a building complex that includes a northern range dating from around 1840 and a front warehouse completed by Lessels and Taylor in 1897. The complex consists of bonded warehouses that are both five and three stories tall, constructed in various phases. The northern range is L-shaped, with a central block added shortly after the original construction, and the front block built around 1880 and 1897. The exterior features cream sandstone with tooled ashlar on the front elevation and return, squared and snecked rubble on the northwest side, some droved ashlar dressings, and coursed rubble on the northern range.

The southwest elevation facing Great Junction Street is five stories high and has eleven bays. It features a cornice and blocking course with two stepped tablets and a former wallhead stack at the center. The three bays to the right were built around 1880, while the remainder was added in 1897. The elevation has single windows, with the five central bays spaced more widely and featuring bipartite windows. There is an off-centre loading door to the right, and a basket-arched door that has been blocked and converted into a window in the penultimate bay to the right.

The northwest elevation, which faces Cables Wynd, has a three-bay return of the front warehouse with matching detailing. This elevation includes a five-story, three-bay warehouse, possibly built between 1840 and 1850, with hoist doors and a gable at the center, and single windows in the outer bays. There is also a three-story, six-bay northern range to the outer left with single windows and a loading door to the outer right.

The northeast elevation, or rear, features a three-story, eight-bay northern range with single windows and a blocked segmental-arched pend in the fifth bay, along with a rendered gable. An inner courtyard contains a five-story building, with the top two floors raised in brick.

The interior of the 1840s Cables Wynd block includes timber floors supported by timber beams and cast-iron columns with saddles. The 1897 section features steel beams with spigot joints and timber Queen-post roofs. The windows throughout the building are barred, with mostly six-pane inward-opening casements, some sash and case windows, and/or lying panes facing Yardheads. The roofs are slate, and there are mutual stacks.
