Susannah Hagan boldly discusses the fraught relationship between key dominating areas of architectural discourse - digital design, environmental design, and avant-garde design. Digitalia firstly demonstrates that drawing such firm lines between architectural spheres is damaging and foolish, particularly as both environmental and avant-garde practices are experimenting with the digital, and secondly remonstrates with an avant-garde that has repudiated the social/ethical agenda of the modernist avant-garde because it failed the first time round. It is environmental architecture that has picked up the social/ethical ball and is running with it, using the digital to very different, and more far-reaching, ends. As the debates rage, this book is a key read for all who are involved or intrigued.
