Constructed with mycelium panels and incorporating traditional chidori joints, the cube-shaped structure operates off-grid while housing all essential living functions in a compact footprint.
5 key facts about this project
01
Constructed primarily with mycelium panels for enhanced insulation and sustainability.
02
Resilient chidori joints provide structural integrity while showcasing traditional craftsmanship.
03
The cube design optimizes living space around essential functions in a compact form.
04
Solar panels and water collection systems support complete off-grid capabilities.
05
Flexible grid layout enables future expansion according to occupant needs.

Nucleus House presents a thoughtful response to the need for sustainable living within a compact design. The residential structure is based around a central cube, which houses essential living spaces in an efficient arrangement. Key areas such as the kitchen, bathroom, office, and living room are positioned around the sides of the cube, while the bedroom sits above. This layout optimizes available space and emphasizes comfort and convenience for its occupants.

Materials Selection
-
The design incorporates a range of materials that align with sustainability goals. Wood is used for its structural strength and warmth, creating a welcoming environment. Polycarbonate is included for its lightweight nature and clarity, allowing plenty of natural light to fill the interior while providing views of the surrounding area.

Mycelium Panels
-
An innovative aspect of the building is the use of mycelium panels, crafted offsite. These panels contribute to the structure's insulation and water resistance. Additionally, they offer fireproofing benefits, showcasing a commitment to eco-friendly materials and construction methods.

Structural Integrity
-
The use of the chidori joint, an ancient Japanese technique, is another critical feature. This joining method enhances the building's structural integrity and demonstrates careful attention to craftsmanship. The joints are noticeable in both the interior and exterior designs, blending traditional techniques with modern architecture.

Sustainable Features
-
The gently sloping roof features solar panels and a water collection system. This encourages an off-the-grid lifestyle by making efficient use of natural resources. The roof design allows the home to function independently from traditional utility systems, highlighting its sustainable nature.

The grid layout also permits potential future expansions. As occupants' needs change, the design allows for flexibility. Each element serves a purpose, resulting in a harmonious blend of functionality and careful design. The result is a home that prioritizes both its inhabitants and the environment.

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.
