Architects David Chipperfield and designer Paul Cocksedge have been selected to create installations for the 2010 London Design Festival's cornerstone project Size + Matter. The exhibition explores the dynamic between materials, manufacturing and a leading designer or architect. Last year's team, Marc Newson and Shigeru Ban, drew  nearly 800,000 viewers.

Size + Matter aims to challenge the public’s perception of everyday materials by creating dramatic temporary structures outside the Royal Festival Hall on the River Thames in central London.  After the show closes, the structures will be sold through Phillips de Pury & Company.

Cocksedge Studio has designed Drop — a series of high, polished, stainless steel discs situated on Festival Terrace which will reflect the buildings and landscape around the Royal Festival Hall. The designer conceived Drop as huge coins that have fallen to earth from a giant’s palm and buckled on impact. The giant coins are magnetized to encourage human interaction, enabling passers-by to place spare pennies on the reflective surface, as a result altering the appearance of the installation. As more pennies are added, the work will evolve in front of the public’s eye as Drop’s surface becomes plated in copper. The ultimate aim is for each penny given, a pound will be donated to charity. Drop is being produced by FORMTEXX using its revolutionary new process for creating double curvature facades.

Chipperfield has created The Space in Between – a cityscape of nine modular blocks which seamlessly transform from shimmering towers in the sunlight to glowing, jewel-like beacons at night. With a light source hidden in the base of each block, each will begin to glow at nightfall. The total composition oscillates between a large still life and a small cityscape where the space in between becomes the protagonist in the balancing of mass and space.
