With Clerkenwell Design Week over, design conscious Londoners are already looking to the next big event of the year, the London Design Festival, which takes place across the capital 14-23 September. This morning, the V&A Museum - the hub of the festival - announced the first details of what to expect from this nine day design extravaganza.

LDF is celebrating its 10th birthday this year and the organisers are promising a special event. Here are some of the things to look out for.

In Trafalgar Square, the BE OPEN sound portal designed by engineering firm Arup and artist development programme Sound and Music will explore the concept of 'design you can't see.' An almost other-worldly structure covered in black rubber, the portal will be an 'immersive environment' where people can go to hear a series of 'three-dimensional soundscapes' created by leading sound artists.

Perhaps the most intriguing project announced so far is Mimicry Chairs by Japanese design studio Nendo, which will create a series of installations based on chairs throughout the V&A Museum. Nendo has created a simple chair archetype, made of pressed and punched metal painted white and giving it an almost ghostlike appearance. Appearing in the main entrance and in 10 other locations around the museum, the chairs will be modified to mimic the particular space and objects in which they have been placed.

Visitors to last year's event will almost certainly remember Timber Wave, an abstract free-standing wooden sculpture by architects AL_A and Arup which cascaded down the steps of the V&A Museum's entrance. This year design meets sculpture again with Prism by architect and designer Keiichi Matsuda. Installed high in the V&A's uppermost cupola, Prism is described as a giant suspended iceberg suspended from the ceiling, which will contently change in appearance as it reflects live data flows.

Alongside favourite events including 100% Design and Tent London, new this year will be a global design forum, which will take place at the new campus of Central Saint Martins college of Art and Design in Kings Cross.

Also new at this year's event will be a series of lighting installations created by Philips and architectural lighting design practice Cinimod Studio.
