3-7 Commercial Street, Dundee

3-7 Commercial Street in Dundee is a warehouse designed by engineers Robertson and Orchar for Wallace Foundry, built in the early 1860s. The building is three stories tall with an attic and features a five-bay arrangement of two, one, and two. It is constructed of rubble sandstone with ashlar dressings and has a slate roof. The windows are margined with corbelled cills, primarily consisting of two-pane timber sash and case frames. The front elevation has a central door with a fanlight and an altered wide-margined doorpiece, flanked by two windows on each side, and five windows on the first and second floors. The right return gable is harled, as the adjoining building has been demolished.

On the rear elevation, there are loading doors on the ground floor with a blind window above. To the left, there is an original slate-hung pyramidal-roofed lift housing on the roof, along with continuous rooflights.

Inside, a light- and crane-well rises through the building, although it has been floored over on the first and second floors. Timber galleries surround the well on the north and south sides, supported by cast-iron columns, and are suspended from timber and wrought-iron composite trussed girders on the east and west sides. The roof features a wrought-iron Polonceau truss with decorative cast-iron struts. There is a spiral staircase with a solid timber newel, resembling a ship's mast. An original hydraulic lift is located at the southeast angle, along with a wrought-iron gantry crane used for transporting metal stock.
