The open building, although a new term of architecture that appeared at the end of the 20th century, is not a new concept as far as traditional and has allowed changes and improvements in structure space and function through generations. This paper discusses the relationship between the main building structures, infill elements, and space through examples in ancient China. It then describes the roles of owners, users, and craftsmen via examples from historical records. In studying these examples, this paper concludes that the craftsmen in ancient China are not merely involved in the period of construction but also in the whole period of use. Thus, the relationship between craftsmen and owners or users can continue for generations in some cases. Finally, this paper suggests one possible strategy for the building industry and technology in the context of sustainable development.postprintInternational Conference on Changing Roles: New Roles New Challenges, Noordwijk, The Netherlands, 5-9 October 2009.
