From Garden City to 15-Minute City: A Historical Perspective and Critical Assessment

The 15-minute city concept was introduced as a post-COVID strategy to support more sustainable recovery from the pandemic and develop complete, climate-sensitive, and resilient neighborhoods. This review examines key neighborhood planning movements to identify the origins of the 15-minute city concept. These include the garden city, neighborhood unit plan, modernist urbanism, post-modern urbanism, and eco-urbanism, which have emerged since the late 19th century. The results of the study show that the concept of the 15-minute city has ten basic characteristics: proximity, density, diversity, mixed-use, modularity, adaptability, flexibility, human-scale design, connectivity, and digitalization. The concept has been successful in advancing theoretical debates on sustainable urbanism. However, some criticisms of past planning movements also apply to the 15-minute city. Similar to the neighborhood unit and modernist urbanism, the concept follows a philosophy of physical determinism, setting goals without specifying how or by what means they will be achieved. At this point, one can only speculate about the future of the concept. A more detailed study of the real-world applications of the concept is needed before one can thoroughly discuss its strengths and weaknesses.
