The Hollow Tree Cabin serves as a thoughtful addition to the urban landscape of Tokyo, aiming to create a space that reconnects individuals with nature. Designed to be a retreat from the fast pace of city life, the cabin emphasizes tranquility and reflection. Its design focuses on organic forms that contrast with the traditional linear structures found in the surrounding area, promoting a sense of harmony with the environment.

Spatial Dynamics

The architectural design features a shift from straight lines to smooth, flowing shapes. This change encourages a connection with the natural surroundings while providing a range of spatial experiences. The layout allows for interactions with light and shadow that enhance the ambiance inside. As one moves through the cabin, the changing shapes create unique experiences in each space.

Materiality

CNC-milled panels made from raw pine timber are central to the structure, providing warmth and comfort. These materials are known for their positive effects on well-being, such as reducing stress and promoting relaxation. Meanwhile, semi-transparent PVC panels invite curiosity. They offer glimpses of the wooden interior while maintaining a connection with the outside environment.

Light and Shadow

A significant feature of the cabin is the skylight, which brings natural light into the interior. This design element pulls the eye upward and creates views of the sky, helping to lessen distractions from the urban surroundings. Light filters through the spaces, resulting in an ever-changing play of shadow and brightness that shifts throughout the day.

Interior Experience

Inside, the layout emphasizes a rise in energy and flow. The vertical orientation invites exploration and cultivates a sense of calm. Smooth transitions between different areas allow for a consistent connection with nature. The raw pine timber enriches the environment, while the semi-transparent panels filter in light, creating soft patterns on the walls that change as the sun moves across the sky.

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.
