Time lawn park is located in Shekou, the experimental site of Reform and Opening up in Shenzhen. The site was originally an idle site with bare surface and disordered trees. It is also the only outdoor open place in a high-density community. Its reconstruction has significantly improved the cultural life of local residents, reconnected and revitalized the community. The project will reuse recycled materials for various facilities to effectively contribute urban carbon emission reduction. Underground Sponge City measures and rain gardens on-site provide the park with a rainwater recycling system. At the same time, 271 original 7 banyan trees and 14 other species of trees that have grown for more than 40 years are retained in the park. Through plant matching, the microclimate environment is improved, and residents are provided with a safe space against disasters such as epidemic diseases, earthquakes and rainstorms, reshaping an ecological resilient, healthy and vibrant public space.
