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.
