Crime prevention through environmental design (CPTED)', 'designing out crime', 'safer by design', 'secured by design' or any of the other 'flavours' of manipulating the built environment to prevent crime, invariably engender an inter-disciplinary approach. This work is frequently the domain of architects, urban planners, police, security professionals, local authority planners and community safety professionals (amongst others). Despite the real work being undertaken by these actors, the diverse disciplinary and practitioner perspectives are insufficiently heard within criminological discourse. We have sought to rectify this by bringing together contributions from built environment and local authority practitioners from England, Australia and New Zealand in this 'Designing out Crime—Voices from the Fields' ebook.
