Literature on organisational space has pointed at the political nature of space. In this article, we explore the relation between the physical space of organisations and change. Through a case study of a media company that successfully designed a new headquarters with the aspiration to become an open, coherentand transparent organisation, we describe and analyse the micropol-itics of organisational space. Using the concept of ‘spatial tactics’, we explain how initial inten-tions with the building design were resisted and renegotiated at the micro level as employees began inhabiting organisational space, by which, we argue, room for change was made. The study contributes to the literature on space and organisational change by providing an empirical account of how spatial tactics matter for making buildings work in change initiatives.
