Designed by Andrew Maynard Architects, Copenhagen Concert Hall is located in Copenhagen, Denmark. Performing venues as a building type are now regularly testing the established adage that form follows function. Coming in all shapes and sizes, contemporary performing spaces have reacted to new demands imposed on them in recent years. Operators, keen to shrug off an elitist image and desperate to attract younger audiences, have been pushing their architects to design more ‘transparent’ venues. Buildings that allow the public to pervade their outer boundaries and even, in some cases, to allow glimpses of rehearsals from the street. Rafael Viñoly ’s recently completed ‘inside out’ Curve theatre in Leicester being a classic example of this new imperative.
