In order to dedicate specific attention to transdisciplinary knowledge production, this book aims to explore (new) hybrid modes of inquiry that allow many of architecture’s longstanding schisms to be overcome: such as between theory/history and practice, critical theory and projective design, the adoption of an external viewpoint and a view-from-within (often under the guise of bottom-up vs. top-down). It therefore offers the reader a mix of contributions that elaborate on knowledge production that is situated in the (architectural and urban) profession or practice, and on practice-based approaches in theory.
