Hillbank Mill, Alexander Street, Dundee

Hillbank Mill, located on Alexander Street in Dundee, was built between 1834 and 1836. This three-storey and attic flax mill features a two-by seventeen-bay design, constructed from red sandstone rubble with an iron frame on the lower floors.

The north elevation includes a central blocked arched cart entry at the ground floor, flanked by three large loading doors, which appear to be original, and five large windows that are placed asymmetrically. There are also four blocked windows in the basement flax store at the eastern end of the mill, below a bipartite window that replaced a larger loading door or engine house window around 1840. The first floor has symmetrically placed large windows, while the second floor features smaller windows.

On the south elevation, the mill has a 17-bay layout with a central depressed arched cart entry, flanked by altered loading doors, two windows, and blocked loading doors beneath where external stairs (now removed) used to lead to first floor doors at each end of the mill. The first and second floor windows match those on the north side, and there is a central dormer hoist above the second floor door. The east and west gables are narrow with skewputts, and there are two arched openings to the east basement. The roof is slate with small skylights, and the first-floor features eight-pane casement windows, while the second floor has six-pane casement windows.

Inside, the mill has an iron-framed basement, ground, and first floor. A single row of cast-iron columns supports cast-iron beams that are stapled to shallow brick arches, which are tensioned by wrought-iron ties and intersected by boxes for gearing, belts, and hoists. The second floor's cast-iron columns support a lengthwise timber beam that holds the wooden floor of a small timber attic.
