Ahvenisto Hospital – familiarly known as Assi
Ahvenisto Hospital – known as Assi – is a next-generation central hospital being built in Hämeenlinna, at the heart of the Kanta-Häme region. Assi brings together specialised medical care, primary healthcare and social services under one roof, creating a seamless and modern service experience for both patients and professionals. Located by the unique nature reserve of the Ahvenisto ridge, the hospital has been designed to be functional, sustainable and future-proof. Construction began in 2021, and the hospital will open for use in 2026.
The new hospital complex has been designed with patient safety, efficient workflows, modern technology and the wellbeing of staff and patients at its core. Assi is being built using an alliance model, in which the client and key partners plan and carry out the project together. This collaborative approach ensures that the solutions are functional, sustainable and based on real needs.
Assi represents one of the largest investments in the future of healthcare in Kanta-Häme. Once completed, it will replace several existing facilities and bring health and social services into a single modern environment. With its thoughtful design, strong professional collaboration and commitment to high-quality care, Assi will strengthen regional healthcare and support the wellbeing of the population for decades to come.
