In a time when almost all of the elements used in the building process are pre-made in a factory or workshop, architectural construction has become a process of assembly. No longer does site labor involve the cutting, joining, and finishing of “raw materials”; instead it entails the installation of components that have been preformed and prefabricated somewhere other than the building site. Construction these days tends to be largely a dry not a wet process, the elements of which are not only precise and exact but meant for specific assembly procedures. The book is narratived of style of facades from Le Cobusier, to functional of glazing of Mies van de Rohe, to formless of Frank Gehry.
