Kohteen tiedot
Laakso Joint Hospital is a joint development by the City of Helsinki and HUS. The project will deliver both psychiatric and somatic hospital facilities in Laakso, and a new building for forensic psychiatry in Ohkola, Mäntsälä. The development includes three new hospital buildings and the refurbishment of two existing buildings, providing more than 900 hospital beds in total. Delivered as an alliance project, it is one of the largest hospital construction projects ever carried out in Finland. SRV is the main contractor. In addition to the new hospital buildings, the project includes extensive underground works and tunnel excavation, carried out by SRV Infra. Below ground, the project will provide a service level for hospital functions, a 550-space car park and an approximately 800-metre logistics tunnel connecting the Meilahti and Laakso hospital areas.
Lifecycle objectives guide both design and delivery
Energy performance and lifecycle-wise solutions are at the core of the project. The new buildings are designed to exceed national energy efficiency requirements by at least 10% and to comply with the EU Taxonomy for sustainable construction. The two existing buildings being refurbished will also see their energy efficiency significantly improved.
Energy production will utilise both recovered waste heat from the area and on-site renewable energy. The building’s waste heat will be recycled efficiently — for example, up to 80% of heat from ventilation air will be recovered.

Hospitals of the future
Laakso Joint Hospital is designed to meet the evolving needs of modern healthcare. Flexible spatial solutions enable adaptable use, making the hospital future-proof and ready for changes in care models or capacity needs. Spaces can be modified or extended as requirements evolve, ensuring a durable long-term investment.

The project is delivered using the alliance model, which emphasises close cooperation between the client, designers and contractor, ensuring transparency, flexibility and shared objectives. Laakso Joint Hospital is a prime example of how strong collaboration can deliver an exceptionally high-quality outcome.
“In a project of this scale, the alliance model has supported shared objectives, a high-quality end result and adherence to the schedule.” - Marko Virtanen, CEO, Kiinteistöosakeyhtiö Laakson yhteissairaala
