Architecture and urban design are typically considered as a result of artistic creativity performed by gifted individuals. Postphenomenology and Architecture: Human Technology Relations in the Built Environment analyzes buildings and cities instead as technologies. Informed by a postphenomenological perspective, this book argues that buildings and the furniture of cities—like bike lanes, benches, and bus stops—are inscribed in a conceptual framework of multistability, which is to say that they fulfill different purposes over time. Yet, there are qualities in the built environment that are long lasting and immutable and that transcend temporal functionality and ephemeral efficiency. The contributors show how different perceptions, practices, and interpretations are tangible and visible as we engage with these technologies. In addition, several of the chapters critically assess the influence of Martin Heidegger in modern philosophy of architecture. This book reads Heidegger from the perspective of architecture and urban design as technology, shedding light on what it means to build and dwell.
