5 key facts about this project
01
Curved wall design enhances interaction with the surrounding landscape.
02
Nesting boxes provide observation access without disturbing wildlife.
03
Composed of volcanic ash concrete, integrating local geological materials.
04
Strategically oriented to maximize views towards significant habitats.
05
Elevated structure minimizes ecological impact on the fragile environment.

The lookout point on Hverfjall Volcano Crater in the Lake Myvatn Region of Iceland represents a thoughtful effort to improve the connection between people and wildlife. Designed to encourage human-bird co-existence, it prioritizes ecological sensitivity while providing a space for visitors to engage with the rich natural surroundings. Set at an elevation of 410 meters, the structure offers broad views of the volcanic landscape, serving as a key location for observing local flora and fauna.

Design Concept

The structure consists of two stories, with the first level open and accessible to everyone. It invites visitors to step into the natural environment comfortably. The elevated second level is specifically oriented to highlight important views, particularly those related to the habitats of Barrow's Goldeneye ducks. This clear focus on observation enhances the overall experience for visitors.

Nesting Boxes

Central to the design are modular nesting boxes placed at a height of 226 centimeters above ground. These boxes are arranged to create a curved wall, encouraging interaction with the surrounding wildlife. Each box features an observation hole at the back, allowing visitors to view the birds without causing disturbance. This design element supports both conservation efforts and educational opportunities, presenting the local ecosystem in a direct and engaging manner.

Materiality

The materials chosen for the project align closely with the geological characteristics of the site. Concrete, mixed with volcanic ash and local tuff, provides structural support while ensuring the building fits well into the natural environment. An outer layer made from volcanic rocks serves as insulation, contributing to the environmental performance of the lookout point.

Environmental Integration

The design pays careful attention to the landscape of Hverfjall, informing the orientation and scale of the structure. By focusing on the south-east direction, it highlights the natural topography. The overall size remains modest, minimizing its impact on the fragile environment. A protective north-eastern wall guards against strong winds, granting visitors a comfortable viewpoint.

The arrangement of nesting boxes not only serves a purpose but also enhances the visual appeal of the structure. This design maintains a strong connection between the built environment and the natural habitat, allowing both to coexist harmoniously.

`
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.
