Jät­kä­saa­ri

The construction of Jätkäsaari began in 2010 and will continue until the end of the 2020s. The area has been prepared for construction by dredging the coastal areas before sea filling and cleaning up contaminated land. The constructability of the land will also be improved by deep compaction. The ground in Jätkäsaari will be shaped to create elevation changes, which increases comfort. The maximum difference in elevation to the original ground level will be 8 metres.

Jätkäsaari is mainly being built one area at a time. The Hietasaari area, which was built first, is already finished, and the construction is progressing in stages towards the shore. See the areas and estimated schedules.

A few old buildings will also remain among the new ones to remind us of the past. The buildings to be preserved are the port’s Huutokonttori on Tyynenmerenkatu, the old general cargo warehouse Bunkkeri, the port’s former administration building Sonckin noppa on Laivapojanaukio and the L2 and L3 warehouses designed by Lars Sonck on Tyynenmerenkatu.

• The Hietasaari and Jätkäsaarenkallio areas have been built first. Hietasaari, located to the east of Hyväntoivonpuisto Park, is already completed, and the focus of construction is on Jätkäsaarenkallio west of the park. The apartment buildings in the area are mainly 7–8-storey, and their facades are plastered and colourful. There are large and sheltered courtyards between the blocks. In total, there will be housing for 6,000 residents.
   
• Saukonpaasi will be built on the banks of the Ruoholahti canal, and the area is largely completed. Saukonpaasi has both apartment buildings and a block of low-rise apartment buildings. There is a marina on the northern bank of the area, and a water bus pier has been planned next to Saukontori. Saukonpaadenpuisto, a park between the apartment buildings, will have a view of Lauttasaari. Saukonpaasi includes housing for approximately 1,500 residents.
   
• Saukonlaituri is named after an old coal pier from the 1920s. Various boat berths for residents and routes along the shores are planned for the area. In the future, you can spend your free time and enjoy the seaside in Tritoninpuisto Park. Altogether, there will be a total of 2.4 hectares of park areas. The tallest apartment building in Saukonlaituri is 16 storeys, but as you get closer to the sea, the number of storeys decreases to 2–3 storeys. Many apartments have a view of the sea. The street-level premises of the residential blocks will house business premises to serve the 3,100 residents of Saukonlaituri.
   
• Atlantinkaari borders the southern part of Hyväntoivonpuisto Park. Hyväntoivonpuisto ends at the seashore, where there are plans for a swimming spot. To the west of Hyväntoivonpuisto, the block structure of Atlantinkaari forms sheltered courtyards. On the eastern edge, the blocks are more open and designed so that as many apartments as possible have a view of the park. Atlantinkaari will have 2,700 residents.
   
• Melkinlaituri is the southernmost residential area of Jätkäsaari, where buildings have 2–5 storeys and the blocks form sheltered courtyards. The construction is scheduled for 2021–2027. Melkinlaituri will be home to 2,000 residents.
   
• The area of Ahdinallas will be built among the last areas in the 2020s next to Melkinlaituri and Atlantinkaari near West Harbour.

• Housing construction will start in the Melkinlaituri detailed plan area in two blocks.
   
• Housing construction will start in the service blocks of Jätkäsaari.
   
• The Royal Park parking facility will be completed in the spring of 2021. The facility will include the Harbour’s parking, among others.
   
• The construction of the Saukonkanava canal will continue. The canal crossing the area of Saukonlaituri will be implemented in stages. Its first part was completed in 2019.
   
• The construction of Saukonpaadenpuisto Park is underway and will be completed in the summer of 2021. The existing park areas and the part of the park to be built now will form a unified park area between the tip of Saukonpaasi and Länsisatamankatu.
   
• The construction of retaining walls for the pedestrian and bicycle bridge across Länsisatamankatu will start.
   
• Atlantinsilta Bridge will be completed in May 2021. Tram lines will switch to routes around the entire Jätkäsaari.
   
• The L3 warehouse will be sold to the presenter of the best concept. The City of Helsinki organised an ideas competition in 2020, the aim of which is to find the best use for the L3 warehouse designed by Lars Sonck on Tyynenmerenkatu.
   
• The art competition Art for the Port will end in the summer of 2021. The competition seeks a public artwork reflecting the identity of Jätkäsaari to be placed near West Harbour.
