This project explores linking the Delaware riverfront with downtown Philadelphia by providing articulating green infrastructure within the strata of low/mid rise buildings.  This strategy relocates the energy and density within a large skyscraper and transposes it horizontally, creating a dynamic connective urban tissue of open space and linear gateways linking the river back to the city. The green infrastructure not only responds to sustainable urban issues of heat islands and rainwater overflow, runoff, and filtration but also provides a network of natural public and private open spaces of nature, estuaries, and wetlands, all of which superimpose an ecological footprint with a dense urban environment.
