The Queen Street facade has triangular Classical pediments at parapet level above each end window bay. These end bays are separated by flanking brick pilasters and have cantilevered balconies on both levels with wrought iron railings consisting of vertical balustrading. The openings contain timber framed multi-paned windows and french doors which open onto the balconies. Ornate floral mouldings are situated on the pilasters to either side of the upper level openings. A deep bracketed cornice runs between the base of the pediments separating the parapet from the remainder of the facade. The parapet has raised sections at each end and in the centre where there is the name "BRISBANE ARCADE" in raised lettering. The Adelaide Street facade has a similar arrangement of openings, but has arched windows in the end bays of the top floor with keystones that extend to the cornice line. A similar cornice occurs above all the other window openings as sun hoods. Cantilevered balconies occur only on the first floor level at each end and in the centre. These have wrought iron railings with diagonal balustrading. The entry to the arcade is central on both facades. The three storey sections extend only part of the distance into the block from both ends and are linked by the two storey arcade. Some of the ground floor shops have been changed from the traditional materials polished timber shopfronts and lead-light windows to be replaced by marble and other modern products. The central space has a void running the length of the arcade crossed by a central walkway leading to the galleries on each side. The upper level is accessed by stairs at each end which retain their original terrazzo finishes. The roof structure above the arcade consists of lightweight exposed steel trusses, and natural light is allowed into the space through clerestory windows on each side. The arcade features art work from the hosting of Brisbane's World Expo '88, namely, "Mirage" by Swiss-Israeli artist Gidon Graetz. Today the Brisbane Arcade features a range of artisan and boutique stores, with several fashion, jewellery and specialist businesses operating out of the location.
