The point of departure of this thesis is regeneration and how it is carried out in two countries, USA and Sweden. Urban regeneration, according to the used definition, seek either to support vulnerable communities by redistributing resources so that they can take advantage of them, or to promote growth and development and through this improve the situation for those in need. The thesis investigates and compare how the projects and their actors formulate, relate to and strive for a better use and higher value of space. The comparison will help to find lessons to be learned across the contexts. The main questions to be answered are: What elements of the projects or programs strive for a higher value of space in a similar way and what does it in different ways? What lessons for future regeneration can be learned from the comparisons? The comparison is based on the assumption that regeneration schemes can learn from one another across contexts and that this is a constructive way to improve knowledge of regeneration. Three cases are investigated. Townhomes on Capitol Hill and Capper Carrollsburg in Washington D.C., USA, are regenerated under the federal HOPE VI program that targets public housing areas. Gårdsten in Gothenburg, Sweden, is regenerated according to the aim of the municipality to decrease segregation. The comparison is made over five themes, organization, public participation, physical regeneration, social programs and social mix. The thesis highlights differences and similarities in the regeneration approaches and show how the cases aim to increase social, cultural and economic capital. The conclusion is that regeneration in USA could benefit from the way of regeneration according to the Swedish case with more participation and a long term focus of the process, and regeneration in Sweden could benefit from a greater focus on design and architecture as in the U.S. cases.
