Temporary buildings can be both interim solutions that no longer serve a purpose at a specific point in time, or projects constructed for special occasions. In all instances, they take possession of a location for a certain time, giving it a new meaning and quality. Architects who create temporary architecture have to plan the disappearance of their work from the outset. The ephemeral nature of this architecture allows architects to focus in a very specific and precise way on what is essential and make very pointed architectural statements. The concept frequently transgresses the borderlines of architecture, art, design, and social intervention, which results in a very unique form of architectural freedom. The frequently experimental nature of temporary architecture provides novel perceptions of buildings, outdoor spaces, and rooms.
