The aim of the research is both practical and theoretical. The practical purpose is to utilize the commissioner’s camp resources and design a summer camp prototype where refugee adolescents can participate and bond with Finland-Swedish teenagers. A social science literature research was conducted on a theoretical level to prepare for the cognitive processes taking place during the camp. The purpose of the theoretical research was to better grasp underlying reasons for eventual conflicts and dilemmas. The research wants to acknowledge a complexity in bridging the gaps between groups and that service design possesses keys to these difficulties. The camp was carried out with a co-production mindset where the leader and Actors daily elaborated on the program and actions during the camp. The main research methods include participatory observations and semi-structured interviews at the camp. The material was presented in empathy maps and affinity diagrams. The result shows that intergroup activities can help the Actors to continue develop a healthy ethnic identity and that the commissioner’s recourses on the island, can be utilized in a positive way. The result shows further how internal-, and cultural differences can create difficulties but that co-design can help overcome these obstacles. Encouraging all participants to pursue friendly relationships between groups is important, even if there at some point are unsecure and negative feelings. The results of the research can be implemented to create and/or update strategies of how to develop ways of sustainable integration and personal development for refugee adolescents in Helsinki.
