Essays revise the definition of the term 'vernacular', from architecture without architects, to disciplinary explorations of the ordinary, modular, and standardised type-forms. Architectural scholars explore a spectrum of issues impacting the notion of 'vernacular': globalisation, digitisation, romanticism, critical practice, socially responsible design and public interest ventures. 'Vernacular' can be imagined as a separate and authentic foil to contemporary life and design. Reports that explore this idea are featured, alongside examples showcasing the radical deployment of 'Vernacular' architecture, not of its forms but of the tactics that are used by activist architects today. Dialectic V will make an excellent part of undergraduate and graduate syllabi on the topic with short and stand alone articles. It also offers thought provoking reading for architects and thinkers interested in nuanced understanding of the contemporary built environment.
