The Connected City is a 124 hectare development plan located at the edge of Hamburg, and is a proposal that links the development’s center to the surrounding agricultural landscape and the central distract of Hamburg. It is the second largest development project in Hamburg after HafenCity. The project came out of a competition organized by the International Building Exhibition (IBA) Hamburg, and analyzed the transformation of the Hamburg landscape overtime, from marshland to a pixelated landscape with clusters of urban development surrounded by suburban landscape and agricultural fields. The development brings together residential, retail and commercial development, with affordable housing alongside recreation. While the project is located outside of the center of Hamburg, a series of green arteries that prioritize pedestrians and cyclists link the Connected City center to the city at large. The project emphasizes self-reliant energy production through high passive solar use by orienting buildings to take advantage of the natural light, a design technique called heliomorphism. Within each neighborood, climate adaptation techniques, including wide canals, rain beds to absorb over flow, linear trenches on the side of streets and concavely graded street profiles are used to protect buildings from flooding. The project was conceptualized as a series of loops at different sizes from the broader region to the neighborhood. A re-use loop focusing on sustainability at the territorial level is complemented by landscape, sport, energy and agricultural loops at the scale of the district, and smaller green loops within neighborhoods.
