The thesis is in the field of information design and specializing on spatial design. The study explores how workplace personalization can take form in an activity-based workplace with flexi-desks. At the time of writing, Mälardalen University is planning to build a new campus in Eskilstuna. The new workplace for the teachers and researchers is planned to be an activity-based workplace with flexi-desks. Earlier studies have shown that in many cases activity-based workplaces have not been used in the way they were designed for. In those cases, there appears to be issues with employees interaction with the physical environment.   The aim of the study has been to investigate what impact and need of workplace personalization have to the teachers in the academy of innovation, design and technology at Eskilstuna University, in order to avoid above named problems with the teachers new activity-based workplace.   Early empirical data in this study is based on interviews, to get the overall picture and to understand how activity-based workplaces work in practice at other organizations. The interviews also defined the functions of the new campus in Eskilstuna, that lead to a mapping of activity zones in the blueprints of the new building. Through studies of literature, a method has been developed that identifies the underlying needs of workplace personalization for the users in this study. The empirical data, together with earlier studies and design theory that puts human behavior first, resulted in a design proposal that satisfies the users needs for storage and personalization. The design proposal is a complement to the flexible workplace.
