The traditional grey world of convention center buildings is flipped on its head by the multi-colored glass facade of the Palais des Congrès in Montreal. Five-foot by 12-foot glass panels in pink, orange, yellow, green, and blue line the west side of the building, along the Rue de Bleury. As the sun hits the glass, it creates a psychedelic rainbow interior, one that constantly evolves with the movement of the sun. As well as creating a the vibrant landmark, the rainbow addition repaired the urban fabric by filling in absent ground level space and created links for public and commercial activity. The extension is the result of a collaboration by Tétreault, Parent, Languedoc et Associés with Saïa et Barbarese Architectes, Ædifica, and architect Hal Ingberg.
