## Project Overview

Located in Iceland, the HRAUN project aims to create a comfortable and ecologically sensitive space that allows visitors to engage with the unique Icelandic landscape, known for its geothermal hot springs and dramatic geological features. This design incorporates elements of traditional Icelandic architecture, specifically inspired by Viking longhouses, to address modern requirements while paying homage to historical context. The elongated form of the building enhances connections to the surrounding environment, providing expansive views from various vantage points.

## Integration with Landscape

Elevated on stilts, the structure minimizes disruption to the rugged terrain, allowing it to coexist with the volcanic landscape. This elevation not only reduces the ecological impact but also optimizes acoustics and thermal dynamics within the building. Large, transparent facades promote natural light and connection with the outdoors, fostering an immersive experience for occupants. The modular design facilitates future alterations and expansions, adapting to the evolving needs of its visitors.

## Material and Environmental Strategy

The material selection reflects a commitment to sustainability and ecological responsibility. The use of aluminum for the structural framework ensures durability while maintaining a lightweight quality suitable for the challenging Icelandic climate. Local sheep wool serves as insulation, effectively managing internal temperatures and reducing energy demands. Geothermal energy systems harness the abundant local resource, providing heating and hot water, and reinforcing the project's eco-friendly approach. The careful application of locally-sourced materials minimizes transportation emissions, supporting regional economies and enhancing the overall sustainability of the design.

The interior layout is organized to accommodate communal interactions and promote flexibility. Spaces such as the living and dining area are designed for social gatherings, while intimate sleeping quarters provide comfort through practicality. Dedicated technical areas ensure that the main living spaces remain functional and uncluttered, further emphasizing the thoughtful consideration of user experience throughout the design.

`
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.
