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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
