TSUGINOTE offers a fresh approach to living in a world where flexibility and sustainability are critical. Located by Lake Chuzenji in Nikko, Japan, the design focuses on creating spaces that support a mobile lifestyle. It uses modern technology and traditional ideas, aiming to meet the needs of its occupants while respecting the environment. The overall concept blends 3D printing with ecological practices, resulting in a building that encourages adaptation and personal connection to nature.

Modularity and Flexibility

A key feature of the design is its modular structure, which allows for easy assembly and disassembly. Residents can customize their living spaces according to their preferences. This user-friendly approach makes it accessible to those without construction experience. The modular printing system streamlines the building process, ensuring efficiency while allowing for personal expression in the layout of the home.

Structural Innovation

The use of 3D-printed joints represents a significant advancement in construction techniques. These joints simplify how panels connect, enhancing both speed and safety during building. Designed to be repositioned easily, these structural elements provide flexibility for changing needs and preferences. They enable occupants to rethink their living arrangements without extensive renovations.

Energy Efficiency

The design prioritizes energy conservation by incorporating insulation into the panel elements. These features enhance thermal performance, keeping the home comfortable year-round. Roof panels are equipped to generate solar power, reducing dependence on traditional energy sources. This focus on energy efficiency aligns with the principles of sustainability, ensuring the home complements its natural surroundings.

Material Considerations

Materials play an essential role in the project, highlighting a commitment to ecological practices. Wood powder and wood filament are the primary components, sourced from local forestry to minimize environmental impact. Liquid glass is used as a fire-resistant coating, contributing to the safety and durability of the home without compromising its overall look.

TSUGINOTE combines modern technology with timeless craftsmanship. The result is a living space that fosters a close relationship between inhabitants and the environment. By prioritizing sustainability and flexibility, the design serves as a practical model for future residential architecture. It reflects a growing desire for homes that adapt to the ever-changing needs of their occupants while maintaining a strong connection to the natural world.

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.
