This paper presents a frame for rethinking how we make cities by exploring the notion of writing beyond a literary act. To contextualize our approach and its application, we draw upon our recent Collaborative Urbanism practice in the Scottish city of Glasgow, UK, to explore the ongoing dialogue between practice and theory in relation to city making. A significant challenge that this emerging practice seeks to address is the need for an effective and authentic method for communities and professionals to come together to co-create new public realm. To understand the perspective our practice is based on, we define two key terms. We employ the term authorship in its broader definition to describe the state of creating or causing effect, specifically the sense of ownership and activation resulting from engaging directly with urban space. By the term inscriptive practice, we are referring to the action of a spatial practice that leads to authorship, i.e. we use collective walking as a means of inscribing urban space. We argue that collective walking when framed as an inscriptive practice enables a different type of authorship through rather than of the site. Our action research area addresses the aftermath of the Modernist project to drive a motorway through the heart of Glasgow in the 1960s and therefore seeks to give people a sense of ownership of parts of the city that have become lost to public use. In this case study we use the practice of night walking to explain how walking enables us to unlock the latent identities, memories and rituals of sites for architectural design and urban choreography. Furthermore, our paper explores, when urban stories are revealed, how they can be used to change what places become in two ways. Firstly, through the act of walking as active and inscriptive in itself. Secondly, having inscribed it and enacted it these places are opened up to a dialogue that can be built upon for future uses. To conclude, we discuss our findings so far and their implications to better understand how we can work with the people of a city to read its secrets and collectively author its future. In this manner, we intend to contribute to the understanding of how collaborative, action-based research may portray and reconstruct places and provide nuanced knowledge of sites by activating them temporally prior to permanent design interventions.
