### Project Overview
Located in Iceland's dramatic volcanic landscape, the design aims to reflect the dynamic nature of the environment through its architectural form and material choices. This structure targets both locals and visitors, enhancing their interaction with the surrounding terrain while serving as a functional year-round center for activities such as skiing and hiking.

### Materiality and Integration
The project employs a thoughtful selection of materials tailored to the local context. Concrete forms the primary structural element, offering durability, while volcanic ash is integrated into the mix to harmonize with the geological character of the region. Wood accents the interior, promoting warmth and comfort, establishing a contrast between the robust exterior and the inviting interior space. This blend not only reinforces the structural integrity but also underscores a commitment to sustainability by utilizing locally sourced materials.

### User Experience and Functionality
The design prioritizes adaptability and fluidity within its interior layout, thereby accommodating a range of activities and fostering interaction among visitors. The facade features a rough-textured appearance that references natural rock formations, visually connecting the building to its environment. Pathways designed for skiing and hiking extend the structure's utility, encouraging outdoor engagement throughout the year. Additionally, sustainable systems such as geothermal heating and rainwater collection support the overall commitment to eco-friendly practices, ensuring both comfort and reduced environmental impact.

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.
