This book, Social Infrastructure: New York, one of a series that documents the Bass Fellowship at the Yale School of Architecture studio led by real estate developer Douglas Durst of the Durst Organization, a leading New York firm known for spearheading sustainable high-rise developments, and architect Bjarke Ingels, founder of Copenhagen- and New York-based Bjarke Ingels Group. Their students explored potential synergies between public and private programs in the design of inhabited bridges crossing major waterways in metropolitan New York. The group traveled to Denmark, Sweden, and Norway to research developments that successfully integrated the needs of numerous stake-holders. The featured projects from the studio demonstrate a diverse range of approaches for combining residential, cultural, and commercial activities on complex and dense infrastructural sites in imaginative and productive ways.
