St Dunstan's College is a co-educational independent school in South East London, England. It is a member of the HMC, and was an all-boys establishment until 1994. Located on an urban site in Lewisham, many additions have been made to the original Victorian building complex, including a large glass-walled dining hall utilising a hyperbolic paraboloid roof requiring no internal supports , the prototype for a similar structure in Calgary. Sports facilities include a sports hall complex, swimming pool, tennis courts, and extensive playing fields for such an urban location. The pre-prep and prep schools are in separate buildings on the same site, one of which was formerly the residence of a previous Headmaster. The school consistently achieves above average examination results at all levels. The International Baccalaureate has been offered as an alternative to AS and A-levels since 2005. A wide range of subjects are offered, with drama and economics indicated as being strong in the most recent Independent Schools Inspectorate report. A large number of sports and games are played, and some pupils have played at an international level.
