The Fjord City project in Oslo (Fjordbyen) is a long-running urban transformation initiative that converted former industrial port areas into mixed-use public spaces. The planning process incorporated extensive participatory design elements, including public consultations, citizen workshops, design competitions, and iterative feedback loops between planners, architects, and residents. The project is notable for its multi-decade timeline, the scale of citizen engagement, and its integration of participatory methods into formal municipal planning processes. It has been studied as a model for large-scale urban co-design. It is particularly relevant in Urban Planning, Design and Public Policy.

Oslo Fjord City Participatory Urban Planning supports participatory, co-design and community-based collaboration and is suited for community-scale initiatives and multi-organization networks in in-person and hybrid settings.

Oslo Fjord City Participatory Urban Planning is an established case study with a solid track record of use across multiple contexts. This case study examines the collaborative practices at City of Oslo, drawing on experiences since 2000.
