Farshid Moussavi This book interrogates further the formfunction relationship of its projects. It focuses particularly on the history of drawing techniques of describing different concepts of function. All is shown through drawings that describe amongst other criteria the structural function [arrangement of activities or materials], the physical function [such as acoustics, traffic, lighting], the psychological function or the social function of built forms. During the 19th and most of the 20th century, discussions of style revolved around pure formalism or pure functionalism. Style, as the way of assembling forms, was trapped in producing consistency and sameness across architectural forms. This publication is the third in a series at the GSD focused at researching a contemporary idea of style in architecture.
