The winner will be announced next February, coinciding with an exhibition of the architect's initial responses. The assessors are chaired by Sir Simon Hornby, chairman of W H Smith, and include the architect Hans Hollein, the painter Michael Craig Martin and broadcaster Joan Bakewell.
Meanwhile, the three finalists in the competition to transform the South Bank Centre, Europe's largest arts complex, have been revealed. All three teams - Michael Hopkins & Partners, the Richard Rogers Partnership, and Allies and Morrison - are London-based. Solutions include covering the entire site with a Crystal Palace-style roof (Richard Rogers). A winner will be announced in September.
