At the convergence of two tectonic plates, a crystal-textured tower rises above a dramatic fissure, showcasing cross-laminated timber elements and offering a Visitor Center that engages visitors with the Earth's geological narrative.
5 key facts about this project
01
Tectonic Tower is positioned directly above a fissure marking the boundary between two tectonic plates.
02
The design incorporates a crystal-textured curved surface that refracts light and sound.
03
Visitor Center integrates exhibition spaces focused on Iceland's geological history.
04
Construction utilizes cross-laminated timber for both structural integrity and sustainability.
05
Sound installations within the tower draw from Iceland's unique natural soundscape.

Tectonic Tower is an architectural undertaking located at the boundary between the Eurasian and North American tectonic plates. The design operates as a landmark, reflecting the geological importance of its setting. Its form conveys the movement of tectonic forces, showing vertical elements inspired by volcanic structures and the textures found within caves. By positioning the tower above a significant fissure, the project connects to its environment and encourages visitors to engage with the Earth's natural history.

Geological Context

The concept is firmly rooted in the geographic significance of the site, emphasizing the separation of two tectonic plates. Tectonic Tower serves as not only a structure but also a bridge between Europe and America. It invites visitors to reflect on geological processes as they experience the physical space. By integrating the architectural design with the landscape, the project highlights the relationship between man-made structures and the natural world.

Visitor Center Functionality

Located at the base of the tower, the Visitor Center fulfills essential functions and provides space for exhibitions. This choice of placement creates an inviting entry point, allowing visitors easy access to both the tower and the surrounding landscape. The center is designed to meet the needs of guests while simultaneously offering educational opportunities. It reinforces the purpose of the project as a place for learning and exploration.

Spatial Organization

The design includes two distinct areas, the Women Cave and Men Cave. Each of these offers a different environment for reflection and interaction, enhancing the overall visitor experience. The arrangement encourages individuals to explore contrasting spaces, promoting a nuanced experience. Furthermore, the layout adeptly distinguishes between public areas and private moments, guiding visitors through the site while maintaining a sense of discovery.

Structural and Environmental Considerations

The structural integrity of Tectonic Tower relies on the use of CLT (Cross-Laminated Timber) walls, which provide both stability and sustainability. Features like the wooden staircase and carbonized wood vertical panels create a cohesive design. This approach aligns with modern environmental standards. Additionally, the project incorporates geothermal energy and a water drill system, emphasizing a commitment to reducing its ecological footprint.

A sound installation at the center of the tower draws inspiration from Icelandic sounds, inviting visitors to engage their senses. This element enhances the immersive experience, creating a lively connection to the geological themes of the project. Through sound, visitors can feel the Earth's presence, enriching their understanding while navigating the architectural space.

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.
