District Pentagon

In 2023, Site is working to remediate gas and coke contamination in the area. I have speculated a dystopia world based on the site: Floods have exacerbated the situation; toxic air has made the surface no longer suitable for human living, leading to the construction of the 'District Pentagon' underground city. The further away from the surface, the safer the people would be. The city is divided into five districts. District one is a waste-to-energy factory, while District 2 generates electricity and water purification. District 3 focuses on hydroponic food production, and District 4 stores and remediates contaminated soil. The centre is supported by each district. The centre people enjoy a healthy aerobic environment, indulging in luxury and singing night and night, regardless of day or night.
