Flexible buildings are intended to respond to evolving situations in their form, operation or location - adapting to new uses, responding to changes rather than stagnating. This innovative book explores this whole new genre of architecture, with projects ranging from advertising hoardings through inflatable architecture, to hospitals and sports stadia. Looking first at flexible architecture's historical precedents, it then discusses four distinct methods by which buildings can be made to respond to user's requirements. Crossing the boundaries between architecture, interior design, product design and furniture design, Flexible is the first book to deal with the entire scope of the topic and will appeal to a wide range of readers.
