With sedum-covered roofs that blend seamlessly into the glacial landscape, the design prioritizes communal interaction while providing an immersive experience for guests observing the aurora borealis.
5 key facts about this project
01
Sedum-covered roofs provide insulation and integrate the buildings with the landscape.
02
Full-length windows enhance views of the aurora borealis and connect guests to nature.
03
The design includes communal gathering spaces to foster social interactions among visitors.
04
Structures are slightly embedded in the terrain, responding to the site's natural contours.
05
Each guest house is self-sufficient, equipped with rainwater harvesting and energy production systems.

The Iceland Thermal Springs Guest House is located in Iceland’s dramatic landscape, where volcanic activity and glaciers shape the land. The design focuses on enhancing the experience of the aurora borealis, allowing visitors to connect with the surrounding nature. The concept is centered on creating organic forms that blend with the unique terrain, resulting in guest houses that invite exploration while offering stunning views of the sky.

Guest House Arrangement

Across the site, guest houses are placed in a manner that appears random, reflecting the natural unpredictability of the landscape. Each structure is oriented northward, featuring large windows that capture expansive views of the Icelandic sky. The monolithic shapes, with their playful and irregular forms, create visual interest. They encourage guests to interact with the architecture, promoting a sense of engagement with both the buildings and nature.

Community Experience

An important feature of the design is the communal areas within the guest houses. The central lobby acts as a gathering space, equipped with a kitchen and sitting room. This layout fosters social connections among visitors. Outdoor spaces include a firepit and a larger hot tub, providing comfortable areas for guests to come together and share experiences while enjoying the scenic surroundings.

Integration with Nature

The architecture integrates deeply with the environment. Some guest houses are partially buried in the earth and others angle to fit the landscape’s contours. This design emphasizes the relationship between the buildings and nature. Sedum-covered roofs reference traditional Icelandic turf design, offering insulation and promoting local biodiversity.

Sustainable Design Practices

Sustainability is a key consideration in the design. Each guest house is equipped with photovoltaic cells for energy generation and systems for collecting rainwater. These features reduce reliance on outside resources and highlight a commitment to environmentally friendly practices. The designs not only respect the environment but also enhance the guest experience by connecting them with the natural landscape.

Natural light filters through the structures, guiding visitors’ attention to the rugged forms outside. The careful arrangement creates a comfortable and engaging space, allowing guests to appreciate both their surroundings and the architecture.

`
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.
