This research and analytical article provides a literature on the large-scale projects across the globe and elucidates the context, issues, and strategies, outcomes and lessons learning from these projects. Among the common concepts, it is possible to distinguish the green wall, water and sewage, and the reinvestment of industrial buildings. The results frequently include the enhancement of the biological diversity, the improvement of the air quality, the raising of the public awareness, and the economic returns.

 

Specific segment of featured projects is characterized by different characteristics influencing the urban scale: some of the projects are the examples of adaptive reuse while others are chosen due to their potential to create a large scale biophilic park with public and recreational functions for people, and some of them are the commercial and residential projects of the future integrated with technology and environmental features.

 

The following are general observations and lessons that can be deduced from these projects: engaging the community, the option of constructing large green space systems in cities. These examples illustrate how the incorporation of biophilic design can make cities more visually appealing, the living conditions of people in those cities better, and also help with preserving the environment.
