Competition overview
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.
Organised 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.
Eligibility and judging criteria
The competition is open to all.
Projects will be judged on the following:
- Integration with nature
- Human scale and intimacy
- Thermal rhythm
- Material sensibility
- Climatic resilience
- Energy and sustainability
- Craft and feasibility
- Atmosphere and poetics
These recommendations serve as guiding principles, not restrictions.
Participants are encouraged to interpret them with creativity, developing proposals that expand on the philosophy of the Iceland Slow Sauna.
How to enter
Participants must upload proposals via the online upload panel.
Submission deadlines
The final registration deadline is 8 April 2026, and the closing date for submissions is 11 May 2026.
