I'm in São Paulo on behalf of Motorola for São Paulo Fashion Week (SPFW), which takes place in Oscar Niemeyer's modernist Bienal building. Second only to his design (see his central sweeping spiral ramp here), the temporary cardboard walls form functional and beautiful spaces within the building. Designed by São Paulo architects Daniela Thomas (renowned for her stage design) and Felipe Tassara, their aim was to take advantage of Niemeyer's building, a feat they achieved very wellâ€”the walls compliment the space perfectly. Made from about 15,000 white cardboard boxes, the modular structures take three different forms: parallel horizontal rectangles, vertical zig-zagging angles and polka-dotted cut outs.They also cleverly cloak scaffolding, as pictured above right. In keeping with the theme of this year's SPFW, the walls are fully recyclable and also make a great backdrop for the riot of color that is Brazilian fashion.
