This book chronicles experimental approaches to the design and production of architectural terra cotta facades and structures. Under the auspices of the Architectural Ceramic Assemblies Workshop (ACAW), a research collaborative supported by Boston Valley Terra Cotta, the largest manufacturer of architectural terra cotta in the United States, architectural firms work with manufacturing to explore material and design innovation. Now in its sixth year, the workshop aims to educate architects about terra cotta through the production of unique prototypes of rain screen façade systems, modular assemblies, columns and structural systems. Architectural Ceramic Assemblies Workshop VI chronicles the work of architectural firms ARO (Architecture Research Office), HOK (Helmuth, Obata, Kassabaum), Studio Gang, Goody Clancy, CookFox Architects, Tod Williams Billie Tsien Architects, and Alfred University/University at Buffalo at the 2021 ACA Workshop.
