This article reads the notion of mediatization through a current example of architectural practice: the Axel Springer Campus in Berlin. Based on current theories of mediatization, it shows how this architectural project for a media firm finds new ways for architecture itself to function as a medium. It argues that architect Rem Koolhaas developed an architectural design that has the capacity to mediate images and interpretations of the productivity of media practitioners, of the relationship between media firm and urban environment, as well as of more general transformations of media work in the digital age.
