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.

`
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.
