The project takes a balanced approach to contemporary architecture, combining functional performance with careful attention to its environmental context. The design responds to practical needs while integrating aesthetic elements that reinforce its relationship to the site. Material selection and spatial organization contribute to an atmosphere that is both efficient and welcoming.

Material Use and Environmental Integration

The structure features a combination of concrete, glass, and sustainable timber. Concrete provides durability and structural support, while large glass panels bring in natural light and open the interior to the surroundings. Timber elements add warmth and reinforce the project’s environmental goals. The distinctive roofline, shaped with a gentle undulation, serves both visual and functional purposes—supporting rainwater collection and improving energy performance.

Spatial Strategy and Sustainability

The interior layout blends open and enclosed zones to support both interaction and privacy. Passive design strategies are embedded throughout, allowing the building to maintain energy efficiency and reduce its environmental impact. Designed with adaptability in mind, the structure accommodates present-day needs while remaining flexible to future changes in use.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
