Site-Reliant Immersive Experiences offers a new theoretical approach to the concept of immersive experiences in relation to space, site and atmosphere. An interdisciplinary work, interweaving philosophy, theory, and creative methods in contemporary art and architecture, this book looks beyond phenomenological accounts of immersion as felt spaces, and technological experiences of VR and AR, to link immersion to actual architectural sites, to the human capacity to contemplate, and to affective atmospheres in art and architectural installations. Fusing atmosphere, sense, and experience, the book introduces a novel vocabulary for understanding immersive spaces in art and architectural contexts from a post-phenomenological perspective. Furthermore, it offers illuminating insights through key reflective case studies of contemporary practices at the intersection of art and architecture, featuring work by Peter Zumthor, Mike Nelson, and Li Xiaodong among others. Bringing together critical theory, affect theory, neuroscience, and new aesthetics to create new methods of praxis in contemporary architecture and art, Site-Reliant Immersive Experiences introduces an innovative framework for understanding immersive experiences within the realm of critical spatial practice.
