examines the development of portable, transportable, demountable and temporary architecture from prehistory to the present day. From familiar vernacular models such as the tent, mobile home and houseboat, to ambitious developments in military and construction engineering, all aspects of portable building are considered. Building on his earlier works and , Robert Kronenburg compares traditional forms of building, current commercial products and the work of innovative designers, and examines key contemporary portable buildings to reveal surprising, exciting and imaginative examples. He explores the philosophical and technological issues raised by these experimental and futuristic prototypes. By understanding the nature of transitory architecture, a new ecologically aware design strategy can be developed to prioritise buildings that 'tread lightly on the earth' and still convey the sense of identity and community necessary for an established responsible society. This book provides a unique insight into this pivotal field of design.
