The exterior fronting on Dundas Street was changed as a part of the redevelopment; with the front entrance moved to the north, aligning with Walker Court, and the installation of a glass and wood projecting canopy known as the "Galleria Italia". The roof of Walker's Court was also redeveloped, with steel truss girders installed, and glued laminated timber used to support the glass-panelled roof, which provides of skylight for the courtyard. The southern portion of the museum building also saw redevelopment, with the construction of a five-storey South Gallery block, and a protruding spiral staircase that connects the fourth and fifth levels of the block. The exterior facade of the South Gallery Block includes glass and custom made titanium panels, and like the Dundas Street fronting, is supported by glued laminated timber. The new addition required the demolition of the postmodernist wing by Myers and KPMB Architects.
