The decision to build a new swimming hall in Visby at Gotland creates opportunities to reuse the old one, Solbergabadet, for another function. The new function, a Performance Art Center, opens up for a study of how a building made for a very specific function could be used for something else in the future. The transformation process brings up questions about material meetings and how the earlier function as a swimming hall could be a part of the new design process and architecture. By reusing a part of the interior structure as a stage and adding a new reusable structure that is more adapted for the new function, the proposal highlights the architecture of transformations of different types of buildings that also will be more important in the future. By this, the history of the building and the earlier function will still be alive but in a new shape in combination with components that the new function requires.
