A rotating microhouse with bamboo catchment systems efficiently integrates sustainable living with compact functionality, providing a flexible space for everyday life.
5 key facts about this project
01
Rotating mechanism allows seamless transition between living functions.
02
Bamboo water catchment system enhances sustainability and efficiency.
03
Modular structure provides flexible use of space in compact design.
04
Vertical garden integrates greenery into the living environment.
05
Stationary central module offers dedicated storage and entrance area.

The design focuses on a microhouse that features an innovative rotating mechanism to improve both space usage and functionality. Positioned within a natural environment, the microhouse captures the feeling of being in a tree house, giving residents a unique view of their surroundings. The concept prioritizes modular elements that can adapt to the needs of the occupants, allowing for a flexible connection between indoor and outdoor areas.

Design Concept

At the heart of the microhouse is its ability to rotate 180 degrees, similar to how a ferris wheel operates. This rotating feature allows for an easy transition between different activities within the space while maintaining stability. The building is organized into three separate modules: two movable side modules that each offer multiple functions, and a stationary middle module used for storage and entrance. This layout maximizes the small footprint and creates versatile living spaces.

Spatial Organization

The microhouse includes essential areas for everyday life, such as a kitchen and washroom combined, dedicated storage, an entrance, and a bedroom that also serves as an office. This practical arrangement separates active living areas from more private spaces. Cooking and relaxation occur in distinct zones, while showering and sleeping areas are thoughtfully placed to enhance comfort and usability for the inhabitants.

Materiality

Material choice is critical for the design, focusing on performance and ecological impact. Bamboo is used for the outer skin of the microhouse, chosen for its flexibility and ability to support a vertical garden. This adds greenery to the space while also improving air quality. Iron wire strengthens the vertical garden structure, and polycarbonate sheets serve as a thermal regulator, allowing natural light to enter while retaining heat. Light plywood is included for its balance of weight and strength, providing practical finishes for interiors and built-in furniture.

Sustainability Strategies

The microhouse incorporates thoughtful environmental practices, particularly in water management. Rainwater is captured using bamboo catchment systems and purified through natural stone filters, making it suitable for kitchen and bathroom use. The design also includes greywater recycling to support irrigation for the vertical garden. A compost toilet system processes waste, returning nutrients back into the garden. This comprehensive approach promotes a living experience rooted in sustainability and environmental awareness.

The overall design presents an adaptable living space where rotating modules, sustainable materials, and efficient water systems come together. It offers a modern lifestyle while emphasizing care for both personal comfort and the natural world around it.

`
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.
