The observation deck project is located on the Diamond Circle tourist route in northern Iceland, within the Hverfjall volcano crater. It serves as a space for visitors to experience and connect with the nearby geological features, including Lake Mývatn and the distinctive lava formations of Dimmuborgir. The design focuses on the idea of observation, featuring a triangular planar structure that creates a visual and experiential link between the architecture and the natural landscape.

Design Integration

The design concept emphasizes observation and perspective. The triangular shape resembles a prism, which relates to humanity's ongoing interest in light and optics. Visitors enter through two central volumes that guide them into the experience, encouraging both personal reflection and a sense of community among those present.

Functionality and Flow

The layout is designed to enhance visitor experiences. As guests enter, they find an information panel that outlines local attractions and offers insights into the area's unique features. From the entry ramp, visitors have the option to explore the first level, which includes an amphitheater with wooden seating. This space promotes relaxation and social engagement. For those who choose to ascend, the upper level culminates in a loop that provides expansive views of the Mývatn region, strengthening the connection between the structure and the surrounding environment.

Materiality

Materials selected for the deck include weathering steel, glass, and larch. These materials were chosen to resonate with the rugged volcanic landscape. Weathering steel adapts over time, developing a surface that aligns with the area’s natural look. The glass elements create transparency, allowing uninterrupted views and fostering a direct relationship between visitors and the landscape. Larch adds a warm touch, enhancing the tactile experience of the design and grounding it in its setting.

Spatial Dynamics

The overall shape and design of the observation deck create interesting spatial dynamics for visitors. Each area offers different viewpoints, allowing people to take in the geological formations and atmospheric conditions of the region. The combination of light and shadow enriches the experience, making the relationship between the built form and the Icelandic landscape feel more engaging.

`
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.
