More news ahead of September's London Design Festival event.

Both Marc Newson and Shigeru Ban have been commissioned by the organisers of the London Design Festival to create installations for it's annual Size + Matter initiative. The aims of this project are to challenge the perception of the everyday materials used, by creating dramatic temporary installations outside the Festival Hall which will be on display from 19 September, the opening date of the Festival, until mid - October.

Shigeru Ban has designed a tower made from cardboard which will soar over the embankment walkway and be visible as a new addition to the South Bank skyline. Made from cardboard tubes, the tower is articulated by metal joints, a system similar in design to the system used by Ban in his construction of a bridge, boathouse and various pavilions around the world. Sponsored by Sonoco, a global supplier of industrial and consumer packaging, the structure will be 22m high and once built, will become the tallest paper tower in the world.

Newson, on the other hand, plumped for a steel structure that is both organic and mathematical. Made of brightly coloured enamelled hexagonal steel panels, it takes the form of an exaggerated funnel, reminiscent of both marine and botanical forms - the source of his inspiration. Sponsored by ArcelorMittal, the world’s leading steel company, the dynamic structure will be seen not only at ground level but also from above, given that visitors can view the structure from the walkways and windows which overlook the space, looking down into it's interior.

The structures will remain in place after the Festival and throughout the Frieze Art Fair in October and will be auctioned by Philips de Pury & Co in due course.
