Jätkäsaari is one of the largest construction sites in Helsinki. The former 100-hectare harbour and industrial area is gradually transforming into a lively and pleasant city district. The construction is well underway. Over a thousand new homes are currently being built.
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 construction of street and municipal engineering is being coordinated with the construction of buildings. However, the streets will be completed after the buildings, as the surface of the streets, such as asphalt, paving stones and kerbstones, can only be built after the buildings are completed. A wide variety of paving stones are used in the surface materials of the streets, especially on pedestrian streets.
In total, one fifth of the area of Jätkäsaari will be covered by green areas. The largest park will be Hyväntoivonpuisto.
