The proposal for the Casablanca Sustainable Market Square competition by Nikolova/Aarsø (N/A) brings together the economic, ecological, cultural, and social aspects of sustainability together. The architects do so with the interplay of medieval Islamic design tradition and contemporary advanced building technology. The architectural concept is developed through the use of the girih tiles as a constantly present design method that elevates its purpose from pure ornamentation to a method of developing architectural composition, spatial organization, structural elements, integration of environmental sustainable technology and strategies, to the planning of flow of people. More images and architects’ description after the break.
