The premeditated decisions of urban plans and designs are in a continuous transformation due to the everyday expectancies and needs of users. People mostly intervene in their built environment in differing scales and temporalities which simultaneously transform a designed space and making it closer to a lived space. Therefore, the emergent user spaces and social practices that occur throughout the everyday life dynamics beyond the expectations of an urban plan are significant to develop a human-centered viewpoint for urban planning and design studies. This study aims at unfolding the theoretical and empirical dimensions of the usually overlooked everyday space and practices which are mostly categorized as ordinary or temporary. In this context, a field study in Yüksel Street has been undertaken to to frame the theoretical discussion on the social and spatial production of urban space and everyday life from an urbanism perspective. The site is a vibrant urban space located in the city center of Ankara that is called Kızılay. Yüksel is a well-connected street to the public transportation stops and has a diverse land use. Since it was laid out following the urban plans in the early years of Republic, the street has been facing social, economic and physical alterations bringing dialectics of designed and lived space together. Despite the initial street pattern maintains today in morphological sense, the altering faces of everyday life and its temporal, spatial and societal impact result in a multi-layered urban entity. This study proposes a theoretical approach which is beyond the dualities and conflicts between physical or social space and temporary or permanent urban rhythms to understand the poiesis of everyday life and space. In this context, there are two channels of study. The first one is using both the archival data on the urban infrastructure of memory (the memory of the past), then the second is to unveil the poiesis of everyday life and space through a field research on Yüksel Street that would make the fluid archive of the ordinary practices and aesthetics (memory enacted in the present). The corresponding research methods on the ethnographic and spatial-visual analysis strengthen the unbreakable bond between social and spatial. The outcomes of the study present the role of the everyday user and the changing urban rhythms on the production of space. This connecting approach explores and presents the spatial qualities of public life practices which are usually labeled as left-over spaces and taken for granted for being evasive or temporary. The dialectic of social life and urban design is essential to grasp user preferences and expectancies from their contribute to the humanoriented urbanism studies.
