"OZOLINI ORDER in NATURE" presents a thoughtful exploration of how people can live in harmony with the natural world. Located within a dense forest, the design focuses on creating a space where the built environment intersects with Nature. The cabin acts as a central point for shelter and reflection, encouraging deep engagement with the surrounding landscape. Overall, the concept highlights the relationship between light, space, and sustainability.

Clearing as a Concept

Central to the design is the idea of clearing, which offers a transition from the thick forest to an open area that allows sunlight to filter through. This clearing is more than just an architectural feature; it creates a space for quiet thought and interaction with Nature. By emphasizing the clearing, the design highlights the contrast between the lively chaos of the forest and the calm sanctuary of the cabin.

Spatial Dynamics of the Cabin

The cabin is strategically placed on one side of the clearing, utilizing a balloon frame system that helps reduce environmental impact. Wooden slats define the structure, arranged thoughtfully to merge with the surrounding trees. This layout nurtures a sense of perception, directing views and guiding movement while establishing a strong connection between the interior and the outdoors through well-placed openings.

Functional Layout and Circle

Within the cabin, design choices clearly separate public and private areas. The entrance leads to a darker transitional space illuminated by a small window, helping to define the meditative residential core and the sanitary facilities. This arrangement allows for an effective flow of movement while ensuring that all spaces are comfortable and easily accessible.

Design Elements

Important details include a bright trapezoidal space at the center of the cabin overlooking the outer glade, along with a mezzanine sleeping area that enhances the cabin’s height. The fireplace serves both as a warming element and as a cooking space, fulfilling multiple roles within the home. Additionally, a rainwater collection system showcases the commitment to sustainability, promoting efficient management of resources within everyday life.

Wooden slats on the cabin's façade are designed to align with the surrounding trees, creating a visual connection that enhances the relationship between the structure and the landscape. The overall design fosters a deepened appreciation of Nature while providing a practical, welcoming refuge for its inhabitants.

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.
