5 key facts about this project
01
Crafted from rammed earth, the walls reflect the geological layers of the Grand Canyon.
02
The pavilion's shape is inspired by the spiral of an Ammonite fossil.
03

04

05
Narrow entry points enhance the immersive experience of the canyon environment.

The visitor information center at Ammonite Point is located in the Grand Canyon, serving as a space for education and interaction with the natural environment. The design focuses on creating an experience that reflects the geological characteristics of the canyon. It aims to immerse visitors in the region's rich history while providing a comfortable space for learning.

Concept and Spatial Flow

The design begins with a narrow entrance that captures the feeling of walking through a crevice or cave. This unique feature invites visitors into the geological context of the canyon. As people travel through this initial space, they reach a larger area that showcases the fossils found in the Grand Canyon. The transition from a tight entry to a spacious interior encourages curiosity and engagement with the displays.

Connection to Natural Forms

The structure's shape is influenced by the Ammonite fossil, which has a spiral design aligned with natural patterns. This approach enhances the building's appearance and supports a functional layout that guides movement through the space. Curved walls and integrated seating create comfortable areas where visitors can gather and reflect on the exhibits.

Materiality and Contextual Integration

Rammed earth is used for the pavilion's walls, connecting the building to its environment. The choice of material reflects the geological layers present in the Grand Canyon. The color and texture of rammed earth evoke the natural surroundings, anchoring the pavilion in its setting and emphasizing its relationship to the landscape.

Panoramic Viewing Experience

As visitors conclude their time in the pavilion, they navigate through another narrowing space that leads to a breathtaking view of the Grand Canyon. This final experience captures the connection between the built environment and the natural landscape. The careful design of the approach enhances the impact of the view, allowing visitors to appreciate the grandeur of the canyon in a meaningful way.

`
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.
