Snøhetta to Transform Historic Paimio Sanatorium into a Wellness and Diplomacy Hub

Snøhetta, the acclaimed Norwegian architecture and design firm, has been tasked with a significant undertaking: to reimagine Finland’s historically important Paimio Sanatorium. Designed by the renowned Finnish architectural duo Aino and Alvar Aalto, the sanatorium, originally completed in 1933 as a tuberculosis clinic, is set to be transformed into a multifaceted destination encompassing hospitality, wellness, cultural spaces, and a venue for international dialogue.

Masterplan Unveiled

Snøhetta recently released its comprehensive masterplan for the Paimio Sanatorium, developed in collaboration with ALA Architects and Mustonen Architects for the initial phase. The vision prioritizes the preservation of the building’s exterior integrity while introducing carefully considered interventions to accommodate its new programmatic uses. Renderings depict the iconic modernist facade remaining largely intact, with the addition of a new entrance located on the rear facade. Enhancements to the surrounding landscape are also a key component of the plan, aiming to integrate the structure more harmoniously with its natural environment.

Adaptive Reuse of Key Spaces

The masterplan outlines a thoughtful repurposing of several key areas within the sanatorium. The former surgery wing will be converted into a flexible auditorium capable of accommodating up to 200 people. This space will feature a new visitor’s entrance and will boast birch-slatted walls, a design element reminiscent of Aalto’s earlier works, chosen for its optimal acoustical performance. Externally, the forecourt, currently asphalted, will be resurfaced with slate and enhanced with new plantings.

A new spa is planned for the lower level, designed to offer serene views of the surrounding forest, providing a tranquil experience for visitors. The former patient wings are slated to become hospitality accommodations. Patient rooms will be transformed into hotel rooms, and the celebrated sun balconies, a distinctive feature of the sanatorium, will be reopened and integrated into the new hotel experience. The bathrooms for these new hotel rooms will feature new freestanding furniture lined with birchwood veneering, a nod to the building’s original materiality.

Respect for Legacy

Kjetil Trædal Thorsen, a founding partner at Snøhetta, emphasized the firm’s deep respect for the legacy of Aino and Alvar Aalto. “With profound respect for the legacy of Aino and Alvar Aalto—and particularly the Paimio Sanatorium—we approach this project with the ambition of opening the site for thoughtful future use,” Thorsen stated. He added that “Grounded in research, each intervention is carefully considered, preserving the building’s integrity while allowing it to evolve.”

This approach has been lauded by Mirkku Kullberg, the Paimio Foundation’s CEO, who, along with curator Joseph Grima, has been instrumental in discussing the future of the Paimio Sanatorium beyond its original healthcare function. Kullberg described Snøhetta’s masterplan as “a thoughtful balance between conservation and restorative architecture.”

Aalto’s architectural significance in Finland is underscored by the potential inclusion of the Paimio Sanatorium, alongside several other Aalto-designed sites, on the UNESCO World Heritage list in July 2026. This designation would further solidify the importance of preserving and adapting such seminal works of modern architecture.

The timeline for the construction and completion of this ambitious reimagining has not yet been shared. The project represents a significant effort to ensure the continued relevance and preservation of a vital piece of architectural history, adapting it for contemporary needs.
