Climate change will render existing Red Hook shoreline infrastructure obsolete. To achieve an efficiency of resiliency on a large area of vulnerable land between the Red Hook Houses and the Brooklyn shoreline, this project proposes a thick urban-mat landscape. Red Hook Resilient Mat Ecology seeks to maximize landscape and built space in a low-rise envelope to optimize environmental performance and the capacity for recovery and growth in the Red Hook community. A network of temporary communal living spaces for storm-relief-housing and 24/7 immersive work programs rests on a concrete plinth elevated above a new marshland. Water-cleansing plants filter polluted water from the Gowanus canal through the designed ecology, generating clean non-potable water for community use. Gardens of bioswales and berms regulate marshland water levels while offering constructed views of preserved industrial buildings. Green space and built space merge to form a new interpretation of the pictorial as an integrated urban system.
