GRAMMAR OF DESIGN is a design workshop created by NOSIGNER. The content is based on Tachikawa’s graduate thesis, which studied the similarity of language and design. Extracting the general ideas that are common to the concept of historical masterpiece designs, we organized the rules of design, just like the “grammar” of language. The Grammar of Design has been introduced as innovation programs at companies such as SCSK and as a lecture at Musashino Art University and University of Tokyo i.school program. Many great ideas have been produced from this practical workshop.
