David Adjaye has designed this pavilion as part of London Design Festival 2008’s Size and Matter initiative. It will be open to the public 24 hours a day in Southbank Centre Square for a month from mid-September.

Named Sclerae, the 8m x 5m elliptical structure is formed of two circular chambers made of American tulip wood. Adjaye said: “It means two things… the domain of parentheses ie space from my viewpoint, or the outer enclosure of the eyeball.”

Visitors will first enter the smaller chamber and experience the pavilion’s materiality, and then pass into a wider space with a view of the London Eye.

The London Design Festival runs from September 13 to 23, and includes among other events an installation by Jamie Hayon in Trafalgar Square; Design-Nation’s Eureka, bringing together designers, manufacturers and retailers; breakfast talks hosted by the Financial Times; and a sustainable design hub run by Arup.

The London Design Medal, won last year by Zaha Hadid, will be announced as part of the programme.
