Architect is joined on the shortlist by Foster + Partners, Office for Metropolitan Architecture, Haworth Tompkins and Glenn Howells

David Chipperfield Architect's America鈥檚 Cup building in Spain and Museum of Modern Literature in Germany are among the six buildings shortlisted for this year鈥檚 RIBA Stirling Prize.

They compete with the redevelopment of the late 19th century Dresden railway station by Foster + Partners, Porto鈥檚 concert hall Casa da Musica designed by the Office for Metropolitan Architecture, the Haworth Tompkins redesigned Young Vic Theatre in London and the Savill 好色先生TV, a modern park pavilion and visitor centre, designed by Glenn Howells Architects in Windsor.

RIBA president Jack Pringle said: "These ambitious projects are the very best in contemporary architecture, reflecting the work of our members in Europe as well as the UK. The RIBA鈥檚 best architects have long found some of their most interesting commissions in continental Europe, but perhaps it is up to UK clients to ensure a better representation of buildings in Britain in future years鈥 shortlists."

The 拢20,000 prize is awarded to the architect of the building that has made the greatest contribution to British architecture in the past year. The 2007 judges include Tom Bloxham, Alain de Botton, architect Louisa Hutton and RIBA President Sunand Prasad.

The winner will be announced in October at the Camden Roundhouse.
