Making cities health-promoting places is an evolving theme. Numerous studies confirm the health-promoting qualities of contact with nature and problems resulting from the deprivation of access to public green spaces. Easy access to safe and inclusive public green spaces is still one of the long-lasting problems of urbanized areas around the globe. It is one of the sustainable development goals, SDGs, proposed by the UN: 11. Make cities and human settlements inclusive, safe, resilient and sustainable. Point 11.7 By 2030, provide universal access to safe, inclusive and accessible, green and public spaces, in particular for women and children, older persons and persons with disabilities. The major question is how to implement this goal in practice and design cities to provide easy access to safe and inclusive public green spaces. One of the important concepts for sustainable urban development is the urban block, Macrolot, coined by Christian de Portzamparc, which led to the new urban morphology of eco-neighborhoods in France. It combines the traditional, walkable urban grid with the Le Corbusier vision for a healthy modernist city offering daylight, fresh air, and greenery for everyone. Among the advantages of this particular urban morphology are the increased presence of green spaces and possibilities for placemaking. Studying the effects of the urban form of the Macrolot is of great significance for sustainable urban development. In this study, five neighborhoods—three eco-neighborhoods from France designed according to the open urban block, Macrolot urban morphology, ZAC Massena, ZAC Trapeze, and ZAC Clichy-Batignolles, and two award-winning developments from Poland, Riverview and Ostoja Wilanów—were chosen as case studies. The application of the Macrolot concept to sustainable urban planning and design and the possibilities for operationalization of the SDG—11. Make cities and human settlements inclusive, safe, resilient and sustainable—are discussed. This study offers valuable evidence to inform urban planning and design.
