This color-illustrated book highlights the work of ON-A, an architectural laboratory in Spain centered on reconnecting people with the natural environment through urban architecture. Material is grouped according to the four themes of design and geometry, sustainability, emotion and lifestyle, and technology, materials, and techniques. Each section begins with conversations between ON-As founders Eduardo Gutierrez and Jordi Fernandez, and this books editor Ricardo Devesa (School of Architecture of Barcelona), as they introduce concepts related to the architectural and urban planning projects profiled in the section. Examples of projects around the world include individual residences, high rises, parks, campuses, hotels, and entire neighborhoods. Several projects feature smart mesh or structural mesh. The book contains a wealth of color and b&w photos and illustrations. Annotation 2022 Ringgold, Inc., Portland, OR (protoview.com)
