Buildner invites architects worldwide to participate in the Iceland Slow Sauna competition, an exploration of how architecture can shape rituals of heat, light, and renewal. Set against the mystical backdrop of Lake Mývatn in North Iceland, participants are challenged to design an intimate retreat that unites a sauna and a greenhouse into one seamless experience. The brief asks how space, material, and atmosphere can heighten the rhythm between warmth, silence, and growth.

Organized in collaboration with Óli and Bianca, the couple behind Slow Travel Mývatn, the competition reflects their philosophy of sustainability, authenticity, and slowness. The project seeks architecture that is thoughtful, resilient, and deeply attuned to nature — a crafted sanctuary that extends the ritual of renewal beyond the sauna itself.

The total prize fund is €10,000. The final registration deadline is April 8, 2026, and the winners will be announced on July 7, 2026.
