21 Robertson Street

21 Robertson Street is a commercial building constructed between 1850 and 1859 as part of a terrace. It was designed by CF Reeks and AJ Humbert for Patrick Robertson, MP, of Hastings. Around 1924, an Art Deco shopfront and interior were installed.

The building has a shop on the ground floor with accommodation above on three upper floors. The front elevation is stuccoed, with a timber and glazed shopfront. The rear is of brown brick, and the roof is tiled.

The shopfront is in an Art Nouveau style, featuring a moulded fascia above a curved window flanked by sinuous wooden pilasters on the left and a narrow, curved section containing shelving on the right. Both sides have marble stall risers. The recessed doorway has rococo-style floral motifs on the door and a square fanlight. The entrance porch has a mosaic floor of turquoise tiles within a chequered border. A roller shutter is positioned at the top of the shopfront.

The upper floors each have two four-pane sash windows with enriched window surrounds, with cornices over the first- and second-floor windows. A modillioned cornice runs at eaves level.

Inside the ground-floor shop, the ceiling has a sunburst design with ovolo moulding. Two curved shelves with anthemion motifs are on the right-hand wall.
