Cracks in a Corten steel exterior reveal an architectural valley leading to geothermal access, merging natural fissures with the structure's function as a visitor center and viewing tower.
5 key facts about this project
01
Cracks in the structure reveal different materials to symbolize warmth within the visitor center.
02
The entrance is designed as an architectural valley, guiding visitors toward geothermal springs.
03
Corten steel develops a weathered patina, enhancing integration with the natural landscape.
04
The monolith's incomplete design invites contemplation about environmental fragility.
05
Light filters through the cracks, creating dynamic shadow patterns inside the space.

The Tectonic Monolith provides a striking engagement with its geological setting. Located in an area known for geothermal hot springs, the design draws inspiration from tectonic plates, presenting a form that is broken but cohesive. As a combination of a viewing tower and a visitor center, it enhances the experience of the surrounding landscape while focusing attention on the delicate balance of nature. The concept emphasizes how built structures can harmonize with their natural environments.

Spatial Configuration

The entrance is located within an architectural valley that directs visitors toward the geothermal features. This configuration transforms entry into an experience, guiding people from the outdoor landscape into the comforting interior of the building. The pathways invite exploration, making it easy for visitors to engage with their surroundings while moving toward the warm heart of the structure.

Material Expression

Timber and Corten steel are vital to the building's visual character. Timber provides an organic warmth that contrasts with Corten steel, known for its rugged and weathered finish. The stark materials are thoughtfully chosen; together, they create a dialogue between human construction and the elements. Over time, the Corten steel develops a rich patina, further aligning the structure with the geological environment that surrounds it.

Design Interpretation

The monolith’s cracked form serves to highlight themes of incompleteness and change. This design choice sparks thoughts about the ongoing processes found in nature. The structure appears as if it is still evolving. Cracks at the pinnacle enhance this idea, prompting visitors to consider their relationship with the environment. It also invites contemplation about the necessity of caring for the natural world.

Inward Reflection

Light and shadow play significant roles within the Tectonic Monolith. As natural light filters through the cracks, it creates varying atmospheres that change throughout the day. This interaction not only showcases the textural qualities of the materials but also enhances the sensory experience for those inside. Such details deepen the connection between architecture and landscape, immersing visitors in a thoughtful journey through space and time.

`
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.
