Market Arcades installs a fresh food market at the intersection of Broadway and Park Row, adjacent to City Hall Park. The assembly of structures, made of sidewalk-shed scaffolds from around the city and moveable panels, celebrates the entire life cycle of food and demystifies the growth, consumption, and waste process for New Yorkers. Moving counterclockwise, Market Arcades features an urban greenhouse, food storage and restrooms, a market, and a composting center. These forces revolve around a new pedestrian intersection, sheltered under repurposed sidewalk shed, to create a vibrant node between the Financial District and its adjacent neighborhoods. At a closer level, panels hanging from horizontal pipes are made of plastic-bag-reinforced-concrete, and use three plastic bags for every square foot of panel. For the 600+ panels in the structure, more than 10,000 plastic bags will be used in the tensile loops and decorative finishes that remind consumers of their waste practices as they shop at the market. By pairing the right to fresh food with an agile construction typology that is quintessentially New York, Market Arcades offers new life to this luxury food swamp.
