PLACE‐FRAMING URBANITY: The Case of Kalasatama, Helsinki

International Journal of Urban and Regional Research, EarlyView.
Abstract Narratives, visuality and symbolic representations are increasingly important in contemporary urban planning and development. This article seeks to understand how urbanity, one of the key goals of Helsinki's recent planning, has been constructed in the Kalasatama regeneration area. The construction of urban image and identity is viewed as soft
