This book examines the interrelationship of representational methods and material systems as fundamental drivers of the design process. Identifying four primary categories of representational logics - point, line, surface, mass - each category is illustrated through four precedent projects that deploy iterative material sensibilities. As a collection, this text provides a comprehensive categorization of the architectural design process.Through the comprehensive definition of categorical typologies, it illustrates the collective capability of this conceptual methodology. By unpacking projects through their specific design devices, the collective analysis reveals the impact of material techniques and methods of representation as a generative tool. Broad in scope, it identifies and uniformly analyses some of the most significant projects from the last century, including:UK Pavilion Shanghai - Heatherwick Studio, Shanghai,ChinaGatehouse - Office dA, Beijing, ChinaMaison Colonial - Jean Prouve, France/Africade Young Museum - Herzog and de Meuron, California USAMontreal Expo 67 - Buckminster Fuller, Montreal, CanadaJean Marie Tjibou Cultural Center - RPBW, Noumea, IndonesiaHouse III - Peter Eisenman, New York, USABarcelona Pavilion - Mies van der Rohe, Barcelona, SpainTel Aviv - Scott Cohen, Tel Aviv, IsraelLos Manantiales - Felix Candella, Mexico City, MexicoYokahama Terminal - FOA, Yokahama, JapanPantheon, Rome, ItalyTres Grand Bibliotheque - Rem Koolhaas, OMA, Paris, FranceBrother Claus Field Chapel - Peter Zumthor, SwitzerlandEmbryonic House- Greg LynnRichly illustrated with consistent, clear and precise line drawings, the book presents a series of iconic precedents through a unique analytical and graphic sensibility.
