5 key facts about this project
01

02
Incorporates charred wooden shingles to improve durability and aesthetic appeal.
03

05
Solar panels integrated into the roof provide energy sustainability for the community hub.

The Spiral Center is a community-oriented architectural project located within the Spiral Ecological Village, designed to promote social interaction and sustainability. The architectural concept revolves around a spiral layout that facilitates movement while creating a sense of unity among its users. The building functions as a communal hub, housing meeting rooms, educational spaces, and areas for physical activities, seamlessly integrating with the surrounding agricultural landscape.

Sustainable Design Principles
This project features a design that prioritizes sustainability through various strategies. The use of renewable materials such as wood and stone lays a strong foundation both structurally and aesthetically. The incorporation of solar panels atop the building emphasizes the commitment to renewable energy, allowing for efficient energy usage. Rainwater collection systems and passive cooling techniques enhance the building's environmental performance, reducing reliance on mechanical systems. The spiral configuration not only holds symbolic significance but also promotes natural ventilation and light access throughout the center.

Integration with Nature
A key aspect of the Spiral Center is its relationship with the landscape. Surrounded by community gardens and agricultural areas, the architecture integrates outdoor spaces that serve educational purposes while promoting local biodiversity. The careful placement of windows and open areas ensures natural light permeates the interior, fostering a connection between the inner and outer environments. The green roofs and garden spaces contribute to cooling and aesthetic value, blending architecture with nature seamlessly.

Community-Centric Approach
The architectural design emphasizes inclusivity and participation among community members. Spaces within the center are meticulously arranged to encourage collaboration and interaction. Flexible areas accommodate various functions, supporting gatherings, workshops, and cultural events. The circular design inherently invites all users to feel at ease, promoting a welcoming atmosphere that strengthens communal bonds.

For a more in-depth understanding of this project, consider exploring the architectural plans, sections, designs, and ideas associated with The Spiral Center, which illustrate its thoughtful approach to communal architecture and sustainability.

`
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.
