Folkwang Museum in Essen, Germany (David Chipperfield Architects) and Stratford-upon-Avon's Royal Shakespeare and Swan Theatres (Bennetts Associates) are also shortlisted. Two London schemes are also in the running for the accolade - the Evelyn Grace Academy (Zaha Hadid Architects) and The Angel Building, (Allford Hall Monaghan Morris).

Meanwhile, the sixth shortlisted project for the RIBA Stirling Prize 2011 is O'Donnell and Tuomey's An Gaelaras in Derry, Northern Ireland.
