Since DETAIL was established, DETAIL editors have held countless discussions with architects and engineers from around the world, from interviews with top international architects to conversations with young, up-and-coming architecture firms. For the first time ever, this book presents a selection of the most interesting interviews of the recent years in one volume: Twelve renowned architects from all over the world - including Santiago Calatrava, Reinier de Graaf (OMA), Toyo Ito, Eduardo Souto de Moura, Alvaro Siza and José Selgas (SelgasCano) - talk about what inspires them, the philosophy behind their architecture, how they work with materials and form, and the actual implementation of their designs. Their inspiring dialogues are accompanied by numerous illustrations.
