The Symbiotic Dome serves as an exploration of adaptability and sustainability within a compact living space. Its design prioritizes ecological balance while also considering the needs of its occupants. The overall approach focuses on creating versatile environments where spaces can easily change based on different activities and daily routines. The concept emphasizes the importance of open areas combined with efficient use of materials to foster a harmonious relationship between people and their living surroundings.

Design Concept

The layout features movable walls that allow for a variety of configurations. Occupants can create distinct rooms for privacy or open up the space for communal gatherings. This flexibility supports various activities, enhancing how users interact with their environment. The design invites a rethinking of traditional living spaces by offering dynamic options that adjust to individual preferences and needs.

Terrace Integration

An outdoor terrace forms an essential part of the design, set apart from the surrounding environment by a grid made from algae-based bio-plastic. This feature adds visual interest while also functioning as a hydroponic garden for small plants. By integrating nature into the living space, the design showcases the potential benefits of greenery, promoting health and well-being among occupants.

Materiality and Construction

The materials chosen reflect a dedication to sustainability and efficiency. The walls are created using a 3D printing process that employs raw earth, providing strength while minimizing environmental impact. Mycelium is incorporated for insulation, both thermal and acoustic. Furthermore, a rainwater collection system installed on the roof supports responsible water management, while algae-filled photobioreactor cells provide an innovative energy solution, functioning similarly to conventional solar panels.

Functional Systems

A significant aspect of the design involves the algae photobioreactor system, which includes a growth tank for harvesting algae and a compressed air inoculation system. This setup efficiently recycles water, utilizing grey water to minimize waste generation. The fast growth rate of the algae enhances energy production, allowing the structure to maintain its operations sustainably. Finally, the building method involves 3D printing technology, which reduces typical construction waste.

The dome's outer layer made from algae bioplastic adapts to various environmental conditions, ensuring the structure remains protected while supporting ecological practices.

`
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.
