The Iceland Cave Tower is located in Vogar Farmland and offers a functional space that blends well with its natural setting. The design focuses on providing essential living and observation areas, allowing users to engage with the surrounding landscape. With an emphasis on practicality and user experience, the building invites those inside to appreciate the unique qualities of the Icelandic terrain.

Structural Design

The layout consists of two levels, with Level 1 featuring key functional areas like a lobby and kitchen. This clear arrangement facilitates movement and accessibility. Level 2 is dedicated to observation, strategically designed to take advantage of scenic views of the landscape. Occupants can connect more deeply with their environment through this thoughtful approach to the building's layout.

Environmental Integration

Details in the elevations show how the structure interacts with the site. The North Elevation includes an entryway, a circular mechanical chase, and a perimeter water collection system. These features effectively manage rainwater, reflecting an informed approach to sustainability that aligns with Iceland's environment. This not only meets practical needs but also respects the local ecosystem.

Site Features

The site includes several important features that enhance both usability and sustainability. Natural stone pathways guide visitors toward the building, creating a clear distinction between the construction and the natural land. The presence of a gray water well and radiant heated benches further illustrates the project’s commitment to practicality while minimizing its environmental footprint. An incinerating toilet is also included, addressing modern waste management in a thoughtful manner.

Utility Infrastructure

The approach to utility planning showcases a focus on energy efficiency and resource management. A geothermal heating system plays a key role in the project and aligns with common sustainability practices in the region. Support systems such as an electrical emergency generator and geothermal well heads are also integrated, ensuring a dependable energy source in a remote area.

The observation area on Level 2 is well-positioned for unobstructed views, giving occupants a chance to appreciate the beauty and ruggedness of the Icelandic landscape while comfortably situated within the tower.

`
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.
