In this timely and expansive book, Wakefield-Rann investigates how emerging disease ecologies are undermining definitions of health and immunity that have persisted since the 19th century, and had a formative influence over the design of not only homes, but entire cities. This wide-ranging account traces the links between the history of medicine, modernist design and architecture, the rise of inflammatory disease, the microbiomes of buildings and humans, antimicrobial resistance, and novel chemical pollutants, to show how indoor environments have made us as we have made them. In highlighting the processes that have been missed in designing perfectly controlled interior habitats, Life Indoors shows the limitations of dominant practices, classifications and philosophies to apprehend current indoor pathogen ecologies.
