11 Bankhead Broadway, Sighthill Industrial Estate, Edinburgh

11 Bankhead Broadway in Sighthill Industrial Estate, Edinburgh, is a large warehouse block built between 1949 and 1950, designed by Stewart Sim of the Ministry of Works. This building showcases innovative and economical functional Modernism, utilizing pioneering techniques for pre-stressed concrete frame construction and anodized aluminium cladding. It stands three stories tall, with two suspended floors supported by a grid of flexible pre-stressed floor beams anchored to reinforced concrete load-bearing piloti columns.

The structure features a ribbed concrete base and plastic interior partition walls, with continuous steel-framed windows set between aluminium panels to provide natural light to the storage floors. The design emphasizes aesthetics with long symmetrical lines, highlighted by vertical glazed stair bays at the ends. Concrete stairs, cantilevered around a blue concrete newel, are exposed through apsidal glass frames, complemented by steel canopy porches supported by steel rod props at the stair entrances. A deep concrete canopy is present at the loading bay on the south side, while a punched aluminium parapet and portholes in cubic lift-shaft blocks are located at the rear (north).

Rainwater and service pipes are concealed, with rainwater channeled down the center of the beams. The columns on each floor were originally painted in three pastel colors. In front of the entrance and loading bay on the south, there are two contemporary flagpoles and short cubic concrete gatepiers at the eastern entrances.
