Today, the feverish churn of demolition and construction that transforms our cities carries profound environmental costs. In this issue, reuse and renewal are explored as urgent acts of design. The magazine seeks to develop and expand this vital movement and engage reuse across multiple scales, from single buildings to downtown streets and the regulatory frameworks that organise cities. Through creative and interdisciplinary thinking, its contents promote the act of bringing new life to what already exists as a powerful brief for designers, their clients, and the communities they serve, examining how architects, planners, and others can breathe new life into what already exists.
