**Project Overview**

Situated north of Vatnajökull National Park and Lake Mývatn in Iceland, "Steinn í Stöðuvatn" addresses the dual challenges of increasing tourism and the preservation of the region’s unique ecological features. The design aims to harmonize with the surrounding volcanic landscape, characterized by geological formations and geothermal activity, while also providing critical infrastructure to enhance the visitor experience and support the local economy.

**Conceptual Framework and Spatial Strategy**

Rooted in organic architecture, the design evokes the region's basalt formations, adopting a form reminiscent of hexagonal pillars found in nature. The building’s organic, non-linear structure diverges from traditional rectilinear designs, fostering an intimate relationship between human activity and the environment. The layout unfolds across three levels, guiding visitors through various functions such as a café, spa, bar, and retail spaces, each seamlessly integrated into the overall design to facilitate exploration and community interaction.

**Materiality and Sustainability Practices**

The project employs a variety of local materials to elevate ecological sustainability. Rammed earth, derived from local excavation spoils, forms the primary walls, while a carefully colored concrete mimics the local terrain, creating continuity between the natural and built environments. Mass timber elements provide structural support and enhance the aesthetic warmth of the interior spaces. Glass is utilized strategically to maximize natural light, forge visual connections with the lake, and promote energy efficiency. The design emphasizes responsible resource management and material reuse, positioning itself as a model for contemporary ecological 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.
