Book excerpt: This edited collection provides an up-to-date account, by a group of well-informed and globally positioned authors, of recently implemented projects, public policies and business activities in Open Building around the world. Countless residential Open Building projects have been built in a number of countries, some without knowledge of the original theory and methods. These projects differ in architectural style, building industry methods, economic system and social aims. National building standards and guidelines have been promulgated in several countries (Finland, China, Japan, Korea), providing incentives and guidance to Open Building implementation. Businesses in several countries have begun to deliver advanced FIT-OUT systems both for new construction and for retrofitting existing buildings, demonstrating the economic advantages of ‘the responsive, independent dwelling.’ This book also argues that the ‘open building’ approach is essential for the reactivation of the existing building stock for long-term value, because in the end it costs less. The book discusses these developments in residential architecture from the perspective of an infrastructure model of built environment. This model enables decision-makers to manage risk and uncertainty, while avoiding a number of problems often associated with large, fast-moving projects, such as separation and distribution of design tasks (and responsibility) and the ensuing boundary frictions. Residential Architecture as Infrastructure adds to the Routledge Open Building Series, and will appeal to architects, urban designers, researchers and policy-makers interested in this international review of current projects, policies and business activities focused on Open Building implementation.
