HAMMARBY SJÖSTAD
Stockholm, Sweden
Stockholm Water Company
Hammarby Sjöstad, or the Hammarby Waterfront City, is an urban redevelopment project that transformed an industrial waterfront that was originally planned to host the 2004 Olympics into a housing, commercial and recreational area. The development was coordinated by the City of Stockholm, and involved 30 developers working on a strategic masterplan whose main goal was to offer a different means of transportation in which 80% of all trips made to and from the district were by public transport, walking and biking. The masterplan divided the district into twelve sub-neighborhoods with different architects and planners working on the details of each space. The proposals were evaluated, and the most effective details in each sub-neighborhood proposal were incorporated into the masterplan. The district uses fuel cells, solar cells, heating from purified wastewater and biofuel, and solar panels across the development. The GlashusEtt, an environmental center located within the community, provides information on sustainability and the wetlands and canals that are part of the district, which does not have private fences, but rather common public spaces. Rainwater drains into canals, is filtered, and also used for heating, while a wastewater treatment plant on site generates recycled sludge that is used to fertilize farmland and forestry in the surrounding areas. The existing planting was preserved, with public avenues forming green corridors through the district, and a nature reserve with planted viaducts that surround the highway leading to the district. The density of the district is similar to downtown Stockholm, with 25,000 residents. Today, the project is a model for sustainable development across the globe, with 13,000 tourists coming to observe the project annually.
