The design centers around a modular cabin situated along popular biking routes in Europe. It serves as a rest stop for travelers, offering shelter and a place to pause among diverse landscapes. The concept focuses on functionality and adaptability, allowing bikers to connect with their surroundings in a more meaningful way. This cabin not only meets practical needs but also enriches the experience of traveling through various terrains.

Functionality and Adaptability

The cabin is crafted to respond to the needs of travelers. When closed, it blends into the landscape, maintaining a low profile. This design choice emphasizes balance with nature. Once opened, the cabin expands, providing space for equipment and personal belongings that bikers carry. This capacity to adapt is central to the design, offering flexibility for various situations.

Innovative Interior Layout

Inside the cabin, storage solutions are designed specifically for bikes, wood, and hanging clothes. This practicality allows travelers to organize their space easily. Rotating walls and an adjustable table enhance the interior’s usability. Whether resting, working, or socializing, the space can serve different functions. Additionally, integrated seating areas create a comfortable environment for various activities.

Engagement with Nature

The cabin features a thoughtful design that alternates between openness and security. While in use, it becomes a refuge for users to rest and appreciate the surrounding landscape. At night, it closes up to protect occupants from the elements. This design promotes a user-friendly experience that aligns with the various rhythms of travel, inviting bikers to immerse themselves in their environment.

The shape and exterior of the cabin reflect the contours of the nearby terrain, enhancing its connection to the natural world. As daylight fades, soft lighting filters through its openings, casting a warm glow that invites travelers to enter and find solace within the cabin.

`
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.
