The Sanctum was designed by Arches as a 1,035-square-metre nature therapy retreat located near Bezdonys, Lithuania. Completed in 2026, the complex consists of elongated gabled buildings arranged around a semi-covered courtyard that supports communal activities and connects to a transformable main hall with panoramic forest views. The exterior combines untreated Kebony-modified pine and natural copper cladding, while whitewashed pine and cross-laminated timber panels create warm interior spaces. Large glazed openings maximize daylight and strengthen the relationship between the buildings and the surrounding woodland.
The retreat's central hall can be divided into two independent spaces using an acoustic partition, allowing the layout to adapt to different programs. Coffered timber structures with integrated glazing bring natural light into the courtyard, which serves as a gathering space for activities including yoga and movement sessions.

What Makes This Trend Stand Out
- Adaptive Wellness Architecture
- Flexible halls, movable partitions, and multi-use courtyards highlight a shift toward retreat spaces that can support varied wellness programming without requiring new construction.
- Biophilic Timber Design
- Natural wood interiors, cross-laminated timber, and expansive glazing create opportunities for hospitality concepts that deepen emotional connection to surrounding landscapes.
- Forest-based Therapy Retreats
- Immersive woodland settings are positioning nature therapy as a premium wellness format for guests seeking restorative experiences beyond conventional spa services.
Sectors Adopting This
- Wellness Hospitality
- Retreat operators can differentiate through architecture-led experiences that combine therapeutic programming, communal gathering, and direct access to nature.
- Sustainable Construction
- The use of modified pine, copper cladding, and timber systems reflects growing demand for low-impact materials that still deliver distinctive design value.
- Experiential Tourism
- Destination travel models are expanding around quiet, restorative environments where design, landscape, and wellness activities form the core attraction.
