There has barely been an important architect in the world for the past century that has not taken advantage of the possibilities of the tentative play and experimentation provided by the design of exhibition sites for trade fairs and world expos. This publication aims at providing a combination of very recent examples from trade fairs and cultural spaces. The spectacular selection of projects ranges from a small stand designed to capture the visitor's attention at a large trade fair, such as the Sci Fi project, to large exhibition sites of museum-like proportion such as the BMW Center, as well as temporary exhibition spaces in cultural centers and permanent showrooms. There are also various interesting examples of innovations in the design of exhibition spaces whose goal is simply to promote with no link to a specific commercial or cultural product.
