Toxic Enigmas aims to provide a new air-centric infrastructural typology in Beijing in order to cleanse the smog-ridden air, and provide refuge with detoxification facilities for the public. Situated over a ring highway, the structure is a filtering wall facing the highest population density while funneling the smog from this high density/high polluting metropolitan area before it reaches the less densified urban areas. This new infrastructure aims to create public interest and ownership of a vital common resource, air.
