The Länsisatama (West Harbour) redevelopment project of the Helsinki City Planning Department is comprised of more than 200 ha of land on the southwest waterfront of the Finnish city. Like other planning projects in the area, this one has generated a lot of public interest. Indeed, the construction of a big new urban district from scratch is rare and raises the question: what is the city of the future? 
The areas covered by Länsisatama project include:
- the residential and office area of Ruoholahti (built in the 1990s)
- Jätkäsaari (used previously for cargo and passenger traffic)
- Munkkisaari (used as a dockyard, part of which will be freed for other uses in 2012)
Within the next two decades, the Länsisatama area will have been transformed into a waterfront city quarter with an estimated population of 22,000, which will enhance the appeal of central Helsinki and its services as a whole.

The Jätkäsaari planning goals
- Produce whole new attractive and ecologically sustainable city district, not just a sleepy suburb
- Meet the everyday needs of residents and workers
- Social well-being
- Construction of the new district is expected to help meet the need for all types of housing, thus easing the housing situation throughout Helsinki:
Another third will be price-regulated free-market housing and right-of-occupancy housing;
The remaining third will be privately funded housing.
- To take advantage of special features of the area (district is almost entirely surrounded by the sea and shipping)
- The buildings have been designed so that the streets do not turn into wind tunnels.
- No residential buildings will be placed in the immediate vicinity of the passenger harbour, because of the noise, bustle and pollution caused by shipping.
- A beach will be created on a sheltered cove in the area.
- Mobility management - New Mobility Culture: non-dependence of private cars in daily traffic
- Cycle paths to serve those living and working in every part of the district.
- High quality pedestrian environment.
- Up to three tram lines.
- Helsinki Metro already runs close to the northern edge of the area.
- Very few streets allowing vehicular access.
- Every residential street will be a cul-de-sac.
- Municipal services be located within walking distance of users' homes.
Another feature that Kaijansinkko was proud of is the green belt winding through the area, reminiscent of Manhattan's Central Park. The green belt is expected to achieve great popularity and importance for the life of the whole district.
- Regenerating urban harbour areas in Helsinki
- Transport infrastructure in the metropolitan region
- Housing development
- Housing repairs
