Book excerpt: Ornament is currently acquiring a renewed status in architecture. As contemporary technologies of design and fabrication introduce unprecedented opportunities to intertwine the constructive logics and expressive articulations of buildings, ornament has re-emerged as a means to explore the interactions between function and decoration, volume and surface, structure and envelope. This book gives a systematic account of the technologies employed in the production of ornament and the strategies of its application today, examining a range of international built examples. Architects with particularly advanced approaches to the question of ornament contribute reports and reflections on their experiences: Sam Jacob of Fashion Architecture Taste (FAT), London; Andreas Hild of Hild und K Architekten, Munich; and Alejandro Zaera-Polo of Foreign Office Architects (FOA), London.
