ammarby Sjöstad is a brownfield redevelopment with mixed uses, carsharing, bikesharing, good transit access and high quality bicycle infrastructure.

Hammarby Sjöstad is recognized around the globe for having implemented an integrated approach to district planning incorporating sustainable resource use, ecological design and low-carbon transport. The 160-hectare district was built on a former industrial and harbor brownfield area located on the south side of Hammarby Sjö (Lake), three kilometers south of the Stockholm city center. The redevelopment has its roots in Stockholm’s bid to host the 2004 Olympics. Hammarby Sjöstad was meant to be part of an ecological Olympic Village. Although Stockholm did not win the bid, planning moved forward and construction of the project began in 1999, converting the site from a run-down industrial area into a modern, environmentally sustainable, mixed-use district with good public transit connections.

Hammarby Sjöstad’s success can be attributed to strong environmental goals that shaped the development plan, incorporating land use, transportation, building materials, energy, water and sewage, and solid waste. The implementation of a holistic environmental profile for a whole district was a new concept when plans began in 1996.

LEISURE & CULTURE

CITY SERVICES

There are around 100 mooring places for small boats along the Sickla Kaj canal.

Sjötadshallen, a sports hall to the northeast of Sickla Udde’s oak-forested hill, was opened in October 2005. Jogging tracks that cross two eco-ducts over the Södra Lanken highway lead directly over to the Nacka nature reserve.

During the summer, Sicklasjön lake is a great destination for swimmers, while in the winter, Hammarbybacken’s slalom slopes are within walking distance.

There is a library at Sickla Kaj and a new culture and theatre center built in Lugnet.

The old Dieselverkstaden factory building, which houses theatrical venues, a library, concert venues and cultural workshops, is also close by in the Sickla area.

The area has preschool and elementary facilities, retirement homes on the banks of Sickla Kanal, and health care facilities.

Commercial services are gradually expanding and the area now has a reasonably wide commercial and retail offering, in addition to the usual convenience goods outlets.

The Sickla Köpkvartar mall, which is easily accessible to Hammarby Sjöstad residents, is home to the majority of retail chains.

TRAMS, FERRIES & CARPOOLS “Tvarbana”, the light rail link from Alvik, has a central route running through Hammarby Sjöstad along the unifying avenue and bus traffic has been carefully thought out, offering several routes into Stockholm city.

A ferry traffics Hammarby Sjö throughout the year, from early in the morning until midnight. During the summer season, a ferry also runs from Hammarby Sjöstad to Nybroviken.

Carpooling is also open to everything living and working in the area. Around 450 members have already joined the carpool, which now has 25 cars at its disposal.

Hammarby Sjöstad adds a new “growth ring” to Stockholm’s urban growth – a modern, semi-open, block-based city of a closed, traditional inner city with more modernistic and open planning. The inner city street dimensions, block sizes, building heights, density and functionality mix are integrated with a new openness, waterfront views, parks and sunlight.

Limited building depths, recessed penthouse flats, large balconies and terraces, big windows, flat roofs and light-colored rendering on water-facing facades embody different applications of a modernistic architectural program, as does the emphasis on durable materials such as glass, wood, steel and stone.

Parks, quays, and walkaways in different styles have been laid out around Hammarby Sjö.

The water areas at the heart of the town comprise a concentrated visual park – the city district’s blue eye.

ENERGY • Combustible waste is converted into district heating and electricity.

• Biofuel from nature is converted into district heating and electricity.

• Heat from treated wastewater is converted into district heating and district cooling. Solar cells convert solar energy into electricity.

• Solar panels utilize solar energy to heat water.

• Electricity must be a “Good Environmental Choice” product, or equivalent.

WATER & SEWAGE • A pilot wastewater treatment plant has been built to evaluate new sewage treatment techniques.

• Biogas is extracted from the digestion of sewage sludge.

• The post-extraction sludge-the biosolidsis used as a fertilizer.

• Rainwater from yards and roofs is drained into Hammarby Sjö, not into the wastewater treatment plant.

• Rainwater from streets is treated locally/ settled and then drained into Hammarby Sjö, not the wastewater treatment plant.

WASTE • An automated waste disposal system with various deposit chutes, a blockbased system of recycling rooms and an area-based environmental station system help the residents sort their waste.

• Organic waste is converted/digested into biosolids and used as fertilizer.

• Combustible waste is converted into district heating and electricity.

• All recyclable material is sent for recycling: newspapers, glass, cardboard, metal, etc. Hazardous waste is incinerated or recycled.
