21 Court Street, Dundee

11 Court Street in Dundee is a three-storey tenement building constructed between 1874 and 1875 by David Clunas and the Concrete Building Company for the Working Men's House Building Association. It features early no-fines mass concrete construction without reinforcement. The building underwent renovation, and buff render was applied between 1982 and 1984.

The west elevation displays a stepped design with alternating five and three-bay widths, corresponding to two and three-room houses. The three-bay houses have a central ground floor pend door with blind single lights above and flanking bipartite windows. The five-bay houses have a similar central door with narrow blind lights above, along with flanking single and bipartite windows. Some central wallhead stacks have been removed. The end houses, numbered 3 and 23, originally had shopfronts that were altered to domestic windows, featuring chamfered angles and corbelled details above the ground floor, along with a simple concrete window and a first-floor cill course.

The rear elevation is plain, with five bays per house and stepped down stair windows. The building has a slate roof with ridge stacks and modern aluminium windows, primarily featuring a two-pane sash and case glazing pattern.

Inside, the stair and stair walls are made of cast in-situ concrete, while the ground floors consist of suspended concrete on joists, and the internal party walls are constructed of brick.
