The wind tunnel at the University of Southampton is used by many outside individuals and organisations, as well as the students themselves. The majority of the athletes winning gold medals in the Beijing Olympics had used the wind tunnel for refining their equipment and posture. Unfortunately, the tunnel is housed in an industrial shed and it is accessed through a maze of corridors. Studio Four were approached to design a new entrance which would raise the profile of the building, create a viewing gallery onto the running bed and providing more appropriate changing facilities, all within the width of the footpath. We have designed a simple steel framed box with curtain wall and aluminium rainscreen cladding. A two storey reception space will allow for past models to be hung from the ceiling. Also on the ground floor there is a toilet, kitchette and office. Upstairs leads in to the wind tunnel building and the viewing gallery, with a parallel entrance for athletes from the changing and shower rooms. The project completed on site in October 2013
