This book is the official catalog accompanying the exhibition Collective Language – Asian Contemporary Architecture at the ASA Architect Expo 2024, organized by The Association of Siamese Architects under Royal Patronage. The content of the book delves into the diversity and distinctions that language brings to hearing, vision, touch, and smell, structured into three chapters: “Sound / Language of Humanity,” “Silent / Language of Shading,” and “Perceive / Language of Ritual.” Through these chapters, nearly 50 architectural firms from 15 Asian countries showcase the contemporary architecture of Asia.
