Utilizing microbial cellulose and transparent PVC tubes, the design showcases dynamic color variations while facilitating natural light interaction, creating a versatile space for community engagement.
5 key facts about this project
01
Utilizes microbial cellulose as a primary construction material.
02
Incorporates transparent PVC tubes for nutrient delivery to the cellulose.
03
Features a dynamic color scheme that evolves with bacterial growth.
04
Designed with hexagonal units to enhance natural light penetration.
05
Encourages interaction between occupants and the surrounding ecosystem.

Micro explores the innovative use of microbial cellulose as a sustainable material within architectural design study. This structure leverages the capabilities of biological materials to create a building that is both functional and environmentally responsive. The design features a series of stacked, elongated hexagonal units, which facilitate natural light penetration and respond dynamically to their surroundings. The application of this material not only emphasizes sustainability but also represents a shift in the architectural narrative towards greater ecological awareness.

Unique Materiality and Construction Techniques

Microbial cellulose serves as the primary building material for this project, derived from a fermentation process involving a symbiotic culture of bacteria and yeast. The resulting product exhibits remarkable properties, such as flexibility and strength, making it suitable for structural purposes. Sisal fibers are utilized for reinforcement, ensuring that the overall structural integrity is maintained while reducing reliance on traditional materials. Additionally, transparent PVC tubes are integrated within the design to enable nutrient transport to the microbial cellulose, reflecting an innovative construction technique that combines biology with architectural design.

The project integrates a color spectrum based on the type of bacteria and fruit used in the growth process, introducing an organic aesthetic that is not commonly found in conventional architecture. The living characteristics of the material create a dynamic visual experience as the colors shift over time, inherently linking the building’s aesthetic to its biological processes. This feature offers not only visual appeal but also stimulates conversations about the intersection of architecture and biology.

Spatial Organization and Interactivity

The organization of spaces within the building is intentional, with a spiral staircase that connects various levels, promoting fluid movement and interaction among occupants. Each floor is designed to foster engagement with the surrounding environment, blurring the lines between indoor and outdoor spaces. The structure's height allows panoramic views and enhances the spatial experience, inviting exploration within this innovative environment.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
