HAMMARBY SJÖSTAD
STOCKHOLM MUNICIPALITY
Sweden
Hammarby Sjöstad in Stockholm is a model urban redevelopment project built on a former industrial site. Started in the mid-1990s, it aimed to be twice as environmentally efficient as typical developments. Initially planned as the 2004 Olympic Village, it continued after the bid failed and is now a global example of sustainable urban living.
Located around Lake Hammarby in Stockholm’s Södermalm borough, the project was mostly completed by 2020 with about 12,700 apartments, shops, and restaurants. Its semi-urban design blends homes, businesses, and retail spaces. Led by the city government, it applied higher environmental standards, resulting in lower emissions and higher property values than nearby areas.

Environmental & Nature
Hammarby Sjöstad follows the Hammarby Model, a closed-loop system linking energy, water, and waste to reuse resources efficiently. Combustible waste powers district heating and electricity, while biogas from wastewater fuels cooking and buses. Buildings feature smart systems, strong insulation, and green roofs that save energy and support biodiversity, all reducing the district’s carbon footprint.
Smart City
Hammarby project uses advanced technology like the Envac Automated Waste Collection System, which moves waste through underground pipes, cutting traffic and emissions by up to 90%. The area also uses smart energy systems and solar panels to meet half its energy needs. These integrated technologies help the district achieve its low-carbon and efficient environmental goals.
Human-Centric
It promotes walkability and low-carbon transport, with all homes within 300 meters of a light rail stop and plenty of bike and pedestrian paths. About 80% of trips are made by walking, cycling, or public transit. Combined with green spaces, large windows, and water features, the design creates a bright, healthy, and lively urban environment.
