Hammarby Sjöstad — A New Generation of Sustainable
Urban Eco-DistrictsHammarby sjöstad is an urban development project directly south of Stockholm's South Island. This is no doubt the most referenced and visited spot among Scandinavian examples of implemented eco-friendly urban developments. The district is developed around Hammarby Sjö (Lake) and when it is finished it will contain around 1 000 apartments for more than 26 000 inhabitants, with 6m2 work space/inhabitant.

Reason to Be Selected

The Hammarby model.One new feature of the Ecodistrict, which has won international recognition, was to integrate several infrasystems in the planning from the very beginning: technical infrastructure, mobility and communication infrastructure, building infrastructure and to some extent green-blue infrastructure. Another strong feature is the system of interdisciplinary planning of physical flows of energy, water and waste. The Hammarby model is today mimicked around the world — e.g. in the Caofeidian Ecocity development in China and in the Swedish SWECO consultant concept Symbiocity in Brasil.


The Hammarby model includes energy conservation measures in which the goal is to reduce heat consumption by 50% and use electricity more efficiently compared to the Swedish average. The share of renewable energy was also intended to be considerably higher than the Swedish average – using bioenergy and incineration of local waste to produce both locally generated heat and co-generated electricity. Large-scale local waste water and stormwater harvest and filtration were also implemented. Storm water devices have high aesthetic quality, which is an important factor in the livability of the neighborhood.


A more sustainable mobility and communications
infrastructureHammarby sjöstad is the first district in half a century in which a tram-line was built as the main commuting traffic mode and the first tram-line ever which was outlined as a cross connection in the southern part of Stockholm. Other features of the sustainable local transport system include an attractive pedestrian and bicycle network, a large carpooling system, a popular ferry connecting the Hammarby sjöstad with Stockholm Downtown's South Island.
A dense green-blue city district with basically positive
aesthetic qualitiesHammarby sjöstad has been planned with a dense settlement structure with typically 4-5 story buildings in a compact neighbourhood outline, but with reasonably spacious green courtyards. The moderate height of the houses and the sufficiently spacious neighbourhoods allow for both wind-shielded and sunny inner courtyards with ample possibilities and incentives to develop both inviting entrance green and common courtyard green, and facilitating small-scale cultivation in micro-garden plots or small greenhouses. There are also established green roofs which are an important part of the storm water system as well as providing important habitat. The area is, at a larger scale, linked to one of the green wedges – the Nacka Wedge with a large ski-slope, vast forests, small fields and several lakes.

Slowly the commercial and municipal services are developing in Hammarby sjöstad. From the beginning it featured a number of restaurants and cafés, whereas the general stores where developed more slowly. This may have been an advantage as the expected wealthy senior population was not the dominant resident category in the Hammarby. Instead the sjöstad mainly attracted young families without or with one child. The result was an initial lack of stores for children and families, municipal services (schools and nurseries) and appropriate green areas. The sjöstads parterre is an important common open space – even if it is mainly restricted to adjacent neighbourhoods and lacks several pedestrian path qualities with cafés and shops.
