Book excerpt: Current planning and design modes of cities are facing challenges of philosophy and form. Past approaches no longer sustain new demands and call for innovative thinking. In a world that is becoming highly urbanized, the need for a new outlook is propelled by fundamental global changes that touch upon environmental, economic and social aspects. The book introduces fundamental principles of timely sustainable urban design, paying attention to architecture, integration of natural features, public urban spaces and their successful use. Readers will learn how cities are transitioning to active mobility by placing the wellbeing of citizens at the heart of planning; making buildings fit nature; supporting local culture through preservation; and including community gardens in neighborhoods, among others. Written by a practicing architect, professor and author, the book is richly illustrated and features meticulously selected international case studies.
