The Mývatn Green Shelter is located in Iceland on a hill that overlooks the Hverfjall volcano and the milky blue waters of the Mývatn Nature Baths. Designed as a greenhouse, it emphasizes a connection to the natural landscape while providing a comfortable space for visitors to enjoy. The design focuses on harmony with the site and the use of natural light, creating a welcoming atmosphere for both people and plants.

Architecture Concept

The design responds directly to the local topography, allowing the building to integrate into the landscape. Varying heights throughout the structure create a fluid form that mirrors the contours of the land. Visitors are guided by the architecture to appreciate both the building and the dramatic natural features surrounding it.

Materiality

Material choices are practical and functional, enhancing the shelter’s purpose. The upper part of the building uses wood and glass, promoting visibility and creating a connection with nature. Light pours in through these materials, supporting plant growth inside and giving the space a warm feel. A black metal base grounds the structure in the volcanic soil, connecting it firmly to its setting.

User Experience

The Mývatn Green Shelter offers more than just a greenhouse. Concrete walls and floors create an experience similar to walking through natural terrain. Outdoor spaces invite interaction, including a stairway that leads to a viewpoint, allowing visitors to take in expansive scenery. Each element encourages connection with the magnificent landscape.

Design Detail

A key feature of the shelter is its ability to grow local produce and prepare meals from those ingredients. This practical aspect deepens the relationship between visitors and the local environment. The combination of bright lighting, flourishing plants, and sweeping views fosters a unique space that celebrates the natural beauty of Iceland.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
