Some 55 practices entered the competition, which was judged by the RIBA president George Ferguson, head of projects Martin Pascoe, and RIBA architectural adviser Simon Allford.
The panel also included Geraldine Mostachfi from the competition sponsor Somfy Dynamic Facade Solutions.
A key consideration for the panel was how architects would be able to work within the interior of the 1930s buildings. It is now waiting to see how the four selected teams respond to the design brief when they submit their proposals in early March 2005.
Ferguson said: 'The jury panel was delighted by the breadth of talent and the types of practice that entered. I was particularly encouraged that a number of relatively small and unknown practices scored very highly and had made it into the panel's top 10.'
