Buildner invites architects worldwide to participate in Iceland Slow Sauna, an exploration of how architecture can shape rituals of heat, light, and renewal. Set against the mystical landscape of Lake Mývatn, participants are challenged to design an intimate retreat that merges sauna and greenhouse into a single, continuous experience.
The brief asks how space, material, and atmosphere can heighten the rhythm between warmth, silence, and growth—and how a small-scale project can become a crafted sanctuary, extending the ritual of renewal beyond the sauna itself.
Organised in collaboration with Óli and Bianca, the couple behind Slow Travel Mývatn, the competition reflects a philosophy of sustainability, authenticity, and slowness, seeking architecture that is thoughtful, resilient, and deeply attuned to nature.
The competition is open to all. Projects will be assessed using the following criteria:
Integration with nature; human scale and intimacy; thermal rhythm; material sensibility; climatic resilience; energy and sustainability; craft and feasibility; atmosphere and poetics.
These criteria are intended as guiding principles rather than restrictions, and participants are encouraged to interpret them creatively.
Participants must upload proposals via the competition’s online upload panel.
The final registration deadline is 8 April 2026. The closing date for submissions is 11 May 2026. Winners will be announced on 7 July 2026.
