5 key facts about this project

The VELOWING project is located on Route des Grottes in Besançon, France, and is designed to meet the needs of cyclists while fitting well into the local landscape. The overall design includes a levitated wing-like structure that minimizes the building's impact on the environment. The building enhances accessibility to natural light in its underground spaces and includes features that cater to both short-term visits and longer stays.

Structure and Access

The building’s design uses two ramps to create distinct access points. The uphill ramp leads to a communal roof area, making it available for public use. In contrast, the downhill ramp provides entry to more private spaces. This thoughtful arrangement allows visitors and longer-term occupants to enjoy their experience without interruption.

Functionality

At ground level, the project integrates essential facilities for cyclists. These include bike parking and repair areas, which are designed to be practical and user-friendly. Spaces for overnight stays are also included, featuring accommodations with beds, bathrooms, and small dining areas. This multifunctional approach provides comfort and support for cyclists, encouraging longer stays.

Materiality

Frosted glass is used in the walls of the building, allowing natural light to brighten the interior. This choice helps to lessen reliance on artificial lighting during the day. Concrete serves as a material for structural components, such as bike racks, ensuring durability while blending into the site’s overall aesthetic. These material choices support both function and connection to the surrounding environment.

A notable aspect is the lower roof, which serves as an outdoor sitting area. This space invites social interaction and provides a resting place in the midst of the natural setting. The design effectively fosters engagement with the outdoors while offering practical amenities for cyclists.

`
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.
