More space for swimming, ball sports and martial arts, gymnastics, dance training, and weight training. In addition to sports clubs and associations, the new facility will also serve two schools and independent sports enthusiasts in the area.
The features planned for the building include:
- For water exercise: A main pool (50 m), a wading and children’s pool, a diving tower and cold pools, and a teaching pool with adjustable depth. The plan also includes a wellbeing pool with massage stations, a jacuzzi, a water play area and a water slide, which has been requested by residents.
- For indoor sports: Ball game halls, group exercise facilities, a skill and motor skill training hall, a gym and several other exercise facilities. More than ten different exercise facilities in total.
- For outdoor sports: The preliminary plan includes features such as a running track for warming up and outdoor gym equipment on the roof of the swimming hall.
- Dressing rooms: Several accessible dressing and washing rooms, including gender-neutral facilities with separate dressing and shower booths. The pool area will feature access to joint saunas and their showers. The swimming hall will also feature ordinary saunas and washing facilities for men and women.

YIT is the main contractor for the Jätkäsaari Swimming and Sports Centre. Construction will begin in early September 2026. Read about the progress of the work and find the construction site contact information on YIT’s website(Link leads to external service).
Construction is expected to last roughly three years. The aim is to have the facilities ready for use in late 2029 - early 2030. The schedule will be refined as the project progresses.
Planning for the Jätkäsaari Swimming and Sports Centre project began in the summer of 2024. The project plan was completed in spring 2025 and was submitted to the Helsinki City Council for approval during 2025.
PES-Arkkitehdit Oy was responsible for the primary and architectural design of the building during the project planning phase. The tear-down of the interior of the Bunker, located on the site of the Sports Centre, began in the spring of 2024 and was completed in August 2026.
850,000 customer visits to increase the wellbeing of Helsinki residents
Jätkäsaari Swimming and Sports Centre will be the most significant addition to Helsinki’s range of sports facilities in decades. The centre will provide sports clubs and associations with even better training facilities and increase opportunities for Helsinki residents to engage in independent physical activity, strengthening their wellbeing and community spirit.
The centre will also enhance the appeal and liveliness of Jätkäsaari and its surrounding area.
The centre will serve all of western and southern Helsinki, and visitors from further away will also be welcome.
The aim is for the swimming hall to have 550,000 visits each year and for the sports halls to have over 300,000 visits. In addition to children and young people, another key user group will be the elderly, whose number is growing in the area. The centre’s facilities will also serve as a hub for physical education for around 1,400 pupils of schools in the surrounding area.
The project will pay special attention to energy conservation and recycling
The building will recover heat from exhaust air and utilise other energy-efficient solutions. The roof will feature a solar power system that will cover roughly 10 per cent of the building’s electricity needs. Space will also be reserved for expanding the system.
The facade materials will be selected in accordance with the principles of circular economy where possible. The partially wood-framed upper floor will feature a facade made from recycled aluminium. The possibility of using recyceled bricks in the facade of the ground floor is being surveyed
Frequently asked questions
The worksite area has already been fenced off due to the demolition of the Bunker, and it will remain the same size for a long time.
The worksite will not have a significant impact on moving about in the area.
Worksite traffic will mainly be handled via the harbour, but there will also be some deliveries coming in via other routes.
Construction will begin in September with earthworks, groundworks and foundation work, which will be the noisiest phase of the project. Work on the building’s structure and facade will be carried out during 2027, and in 2028–2029, work will mainly be carried out indoors.
