The building is known as one of Finland’s architectural icon: Paimio Sanatorium in Finland, one of the most celebrated works of architects Aino and Alvar Aalto, is set for a new chapter as an innovative hospitality and wellness destination.
According to the Finnish State for budget 2026, the State is to contribute 10 million euros to the total renovation and long-term preservation of Paimio Sanatorium in 2026–2029, with a first instalment of €1.5 million included in the 2026 budget.
Norwegian architecture firm Snøhetta has unveiled plans to transform the former tuberculosis sanatorium into a hotel, while carefully preserving the building’s historic character.
Aalto Sanatorium remains indeed an important destination for Finland: since opening to the public in summer 2021, the Sanatorium has welcomed approximately 150,000 domestic and international visitors, highlighting its significance as a growing cultural tourism destination.
Originally completed in 1933, the landmark was designed as a healing environment where architecture, light and nature played a central role in patient recovery.
Under the redevelopment plans, the former patient wing will be converted into a tranquil hotel featuring guestrooms inspired by the building’s original design. Some adjoining patient rooms will be combined to create larger guest suites, while new bathroom facilities will be introduced as freestanding birch-veneer units, creating a contemporary contrast with the historic interiors.
A major feature of the project is the conversion of the former surgery wing into a flexible two-story auditorium capable of hosting up to 200 guests. The venue will feature birch slatted wall elements inspired by the Aaltos’ design language and will support conferences, cultural events and performances. A new visitor entrance will also be added, allowing events to operate independently from the rest of the property.
The redevelopment places a strong emphasis on reconnecting the building with its natural surroundings. The sanatorium’s famous sun balconies, originally designed to give patients access to fresh air and sunlight, will be reopened after years of being enclosed by later glass additions.
A new spa and wellness area will be created on the lower level, offering direct access to the surrounding forest. The addition reflects the original vision of the Aaltos, who considered nature an essential part of the healing experience.
Landscape improvements are also planned with slate surfaces and introducing additional planting to strengthen the connection between the property and its woodland setting.
According to the Paimio Sanatorium Foundation, the project successfully balances conservation with contemporary needs, ensuring the historic site remains relevant for future generations.
The sanatorium operated as a general hospital until 2010. Since 2020, the Paimio Sanatorium Foundation has overseen its preservation and future development. The site is also among a total of 14 Aalto-designed properties under consideration for inclusion on UNESCO’s World Heritage List. A decision is expected in July 2026.
