Unpleasant Design book is a collection of different research approaches to contemporary urban phenomenon in which social control and is inherent in the design of objects and places. With many examples to be found across cities worldwide, Unpleasant Design manifests in the form of "silent agents" that take care of behaviour in public space, without the explicit presence of authorities. Photographs, essays and case studies of unpleasant urban spaces, urban furniture and communication strategies reveal this pervasive phenomenon. With contributions by Adam Rothstein, Francesco Morace and Heather Stewart Feldman, Vladan Jeremic, Dan Lockton, Yasmine Abbas, Gilles Paté, Adam Harvey and many others, the book is in an attempt to recognise this nascent discipline within contemporary design taxonomies.
