This research investigates two neighbourhoods around the train and S-train Ny Ellebjerg in South of Valby, which is a part of Copenhagen. The area, which is a post-industrial area, includes several old factory buildings renovated as office- and workspaces. The research aims to investigate the identity transformation in the area and the influence of the recent development plans in the identity. Therefore, the research questions are: How has the place identity of Ny Ellebjerg changed from being industrial to a densely built neighbourhood and what do the plans indicate for the future? How has the development plans and local plans contributed to the place identity transformation of the Ny Ellebjerg area? The thesis will answer these questions with a triangulation between a content analysis on the involved development plans, local plans and municipal plans, and expert interviews as well as walk-along interviews with residents from the area. The findings of the thesis showed that identity of Ny Ellebjerg has changed from being mainly industrial into a city environment inspired by the forms of the industrial constructions, but with a lot of the buildings perceived as very similar to other areas standardized architecture. The plans for the future indicate that it is necessary to plan with more focus on the residents living in the area. The findings of this thesis showed connections between the wish to preserve the area and turn it into a post-modern, post-industrial area with close ties to its past. The aims of the local plan were not realised fully, since the Følager development was only half built and much of the green areas shown in the illustrations was also found to have not been made, due to it not being directly stated in units in the plans.
