The Grjótagjá Horizontal Viewing Tower is set in a unique geological area of Iceland, located between the caves of Karlagjá and Kvennagjá. It serves as a platform for visitors to observe the striking landscape, which features dramatic geological formations. The design concept emphasizes accessibility, enabling people of all abilities to engage with the natural surroundings. Its architecture harmonizes with the environment, encouraging a deeper connection between visitors and the landscape.

Design and Accessibility

The design includes a gentle slope that leads visitors through the site. This pathway is primarily free of stairs, promoting ease of access for everyone. The incline is set at 1:12.5 (8%), with resting landings every 10 meters to break the journey into manageable sections. Three observation piers extend from the tower, designed to enhance the experience of viewing the landscape. These piers invite visitors to pause and appreciate the beauty of their natural surroundings.

Environmental Integration

Careful planning minimizes the disturbance to the landscape. The structure connects to the ground only at essential points, preserving the natural contours of the area. Visitors can move safely across fissures, allowing them to explore without impacting the environment. This thoughtful approach to design reflects a commitment to sustainability, ensuring that the tower fits comfortably within its setting.

Sustainability Features

Sustainability is a core aspect of the tower's design. Geothermal energy is used for heating, and rainwater is collected from the sloped roof, which is designed to manage snow buildup. These systems showcase effective environmental management, highlighting a responsible approach to building in a sensitive landscape. The focus on sustainability ensures that the structure serves its purpose while remaining considerate of its ecological context.

Materiality and Construction

Locally sourced wood and steel are the primary materials used in the construction. Round timber beams provide structural support, while square-cut wood poles and steel elements form the framework of the tower. These materials were selected not only for their sturdiness but also for their compatibility with the local environment. This choice enhances the connection between the structure and its natural surroundings.

The design includes open areas that allow natural light to enter, creating a welcoming environment for visitors as they engage with the landscape. The viewing platforms provide opportunities for reflection and appreciation of the geological beauty that envelops them.

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.
