The building is constructed in ashlar stone with a slate roof in an "exuberant free style" of architecture. It has a combination of two and three storeys, with attics and cellar. There are ten bays along Hope Street and three along Hardman Street. Its external features include a variety of windows, most with mullions, and some with elaborate architraves, a two-storey oriel window at the junction of the streets, stepped gables, turrets with ogee domes, a balustraded parapet above the second storey, a serpentine balcony (also balustraded) above the main entrance in Hope Street, and a low relief sculpture of musicians and musical instruments. The main entrance contains metal gates in Art Nouveau style, their design being attributed to H. Bloomfield Bare.
