Elements of Architecture focuses on the fragments of the rich and complex architectural collage. Window, façade, balcony, corridor, fireplace, stair, escalator, elevator and toilet: the book seeks to excavate the micro-narratives of building detail . The result is no single history, but rather the web of origins, contaminations, similarities, and differences in architectural evolution, including the influence of technological advances, climatic adaptation, political calculation, economic contexts, regulatory requirements, and new digital opportunities . It’s a guide that is long overdue—in Koolhaas’s own words, “Never was a book more relevant—at a moment where architecture as we know it is changing beyond recognition.” Derived, updated, and expanded from Koolhaas’s exhaustive and much-lauded exhibition at the 2014 Venice Architecture Biennale , this is an essential toolkit to understanding the fundamentals that comprise structure around the globe. Designed by Irma Boom and based on research from the Harvard Graduate School of Design , the 2,600-page monograph contains essays from Rem Koolhaas , Stephan Trueby , James Westcott and Stephan Petermann ; interviews with Werner Sobek and Tony Fadell (of Nest); and an exclusive photo essay by Wolfgang Tillmans . In addition to comprehensively updated texts and new images , this edition is designed and produced to visually (and physically) embody the immense scope of its subject matter: Custom split-spine binding : our printer modified their industrial binding machine to allow for the flexible, eight-centimeter thick spine Contains a new introductory chapter with forewords, table of contents, and an index, located in the middle of the book (where it naturally opens due to its unique spine) Printed on 50g Opakal paper, allowing for the ideal level of opacity needed to realize Boom’s palimpsest-like design Translucent overlays and personal annotations by Koolhaas and Boom are woven in each chapter to create an alternative, faster route through the book Printed at the originally intended 100% size for full readability
