Open Source Architecture is a manifesto for the architecture of tomorrow. It offers a wholly new vision of how architecture can and must adapt to the realities of the 21st century. The authors call for a paradigm shift from the ego-fuelled grand visions of 'starchitects' and their Modernist forebears, to a networked, collaborative, inclusive model that draws inspiration from phenomena such as crowd-sourcing, open access and mass customization. Timely, provocative and passionate, this is a small book packed with big ideas that no architect or designer can afford to ignore.
