Since the beginning of the 2000s, Ronan & Erwan Bouroullec are considered to be amongst the best representative of French design's dynamism and creativity. Working together since 1998, the two brothers worked for numerous manufacturers (Vitra, Cappelini, Kvadrat, etc.), while maintaining an experimental limited edition activity with Galerie kreo. Among their iconic pieces are the Disintegrated Kitchen (1997), the Closed Bed (1998), the Spring Chair (2000), and, more recently, the Vegetal Chair (2009). They also worked with Issey Miyake, Camper, and Kvadrat for the creation of architectural projects. Published on the occasion of the release of their new project, Lianes, Roches & Conques, this book offers a new insight into their creative process, gathering together drawings and sketches, as well as studio, workshop, and gallery photographs. A foreword by Alessandro Mendini, designer and Editor-in-Chief of Domus, and a text by Ronan & Erwan Bouroullec enlight their working process, explaining the path from the idea to the exhibition, and the links between industrial fabrication, design, and signature. As Mendini puts it in this book, 'the studies carried out by the Bouroullec brothers to integrate their design work with the shapes, elements, and ways of nature are becoming increasingly evident'.
