5 key facts about this project

05

The design focuses on creating a cabin in a forest setting. The cabin serves as a retreat for meditation and reflection, allowing visitors to connect with nature. The overall concept emphasizes abundance, capturing the essence of the forest and its many elements. The goal is to offer a space for rest and self-discovery, integrating harmoniously with the natural surroundings.

Spatial Organization
The layout carefully balances communal and private areas, addressing different user needs. This arrangement supports both social interaction and quiet moments, allowing for varied experiences within the space. The design features vertical lines and triangular shapes, reflecting themes of growth and connection to the sky. This encourages a journey through the cabin, inviting users to explore and engage with their environment.

Natural Light and Ventilation
Natural light plays a key role in the experience of the cabin. Large openings are placed throughout to ensure ample sunlight brightens the interior. This design choice enhances the sense of openness and strengthens the link between the indoors and outdoors. Additionally, practical ventilation techniques are implemented, contributing to comfort and aligning with environmentally friendly practices.

Materiality
The main material used is white pine, which serves both structural and aesthetic purposes. This choice supports a connection to the forest, providing durability and warmth. Reclaimed wood is used for external cladding, highlighting sustainability and respect for history. The foundation and heating system utilize rammed earth, promoting not only functionality but also a longer lifespan for the cabin.

The cabin functions as an extension of its forest environment, blending with the landscape while offering a peaceful space for contemplation. The thoughtful use of natural materials, careful lighting, and organized spaces creates a retreat that fosters tranquility and a deeper connection to the surrounding woods.

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.
