The RACS department store (138–152 Powis Street) was built in 1938–1940 in a streamlined Art Deco style. The large, metal-framed windows emphasise the horizontal lines in the faience-tiled gable, set between two end towers. The elegant east tower contains an open stairwell with wrought-iron railings with the letters 'co op' integrated in the design. The west tower is less pronounced and stands over an access road to Mortgramit Square. In 2013-16 it was converted into apartments ("The Emporium"), adding three recessed storeys on top of the restored building.
