The U.K.’s Foreign & Commonwealth Office today unveiled a shortlist of architects who could be tapped to design the British Pavilion for World Expo 2010 in Shanghai. Officials selected six teams from a field of 47 entries; the winner will be announced in September. The finalists are:

• Avery Associates Architects with Adams Kara Taylor, Fulcrum, and Event Communication
• Draw Architects with Arup, DCM Studio, and Graven Image
• Heatherwick Studio with Adams Kara Taylor, Atelier Ten, and Casson Mann
• John McAslan + Partners with Arup and Wordsearch
• Marks Barfield Architects with Price & Myers, Arup, and Imaginatio
• Zaha Hadid Architects with Arup, Metstudio and the Architectural Association School of Architecture Curatorial Projects.

Working within a $20 million construction budget, the winning team will design a pavilion for a one-and-a-half acre site along the Huangpu River in Shanghai. It will house exhibits and technology that showcase sustainable development in the U.K.’s culture, media, sports, education, and business sectors. Malcolm Reading & Associates is working with the British government to manage the competition and act as design advisor.
