The Icelandic Tower Project is an architectural initiative situated at the intersection of the North American and Eurasian tectonic plates. It serves as a multifunctional observation tower that also acts as a cultural landmark, grounding visitors in the historical and geographical significance of the surrounding area. As a tribute to Viking navigation practices, the design aims to create an experience that connects users with both the past and the present.

The architectural form is derived from the concept of a "Sun Compass," incorporating significant elements of Norse heritage into its modern design. The structure features a central floating staircase that guides visitors upward to a prominent observation platform. This arrangement not only enhances the elevation experience but also facilitates immersion in the surrounding landscape.

Innovative Use of Materials and Sustainability

The project sets itself apart from similar initiatives through its innovative use of local materials and sustainable design principles. The exterior primarily comprises local basalt stone, which integrates the building into its geological context while also ensuring durability. Tempered glass curtain walls allow for ample natural light, enhancing the user experience, while maintaining structural soundness.

The incorporation of geothermal heating techniques ensures energy efficiency. Water sourced from local hot springs is utilized for heating and bathing purposes, reducing reliance on conventional energy sources. This dual-purpose strategy illustrates the project's commitment to sustainability while promoting engagement with the local environment.

Unique Structural Design and Functionality

The architectural detailing of the Icelandic Tower Project emphasizes both historical reference and modern engineering. The semi-circular Gateway structure serves as a threshold that signifies transition, allowing visitors to engage both with the architecture and the surrounding nature. This aspect not only speaks to local history but also facilitates social interactions among visitors.

Further enhancing the experience are strategically placed viewing terraces that provide unobstructed views of the landscape. These spaces are designed for contemplation and engagement with the environment, facilitating a deeper connection to the site's natural beauty. Additionally, civic areas embedded within the project create opportunities for communal gatherings, fostering a sense of community.

The design employs a combination of hollow steel sections and steel cables to support intricate designs without compromising safety. A comprehensive drainage system manages the landscape's biological and chemical components, reflecting the project's ecological mindfulness.

Explore the architectural plans and sections for deeper insights into the design and functionality of the Icelandic Tower Project. Understanding the architectural ideas behind this project will provide a fuller appreciation of its unique contribution to contemporary 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.
