The architectural design project titled "Spontaneous Home – The Community Home" is situated in the Spirala Ecological Village in northern Portugal. It is conceived as a response to contemporary societal needs, focusing on community living and ecological sustainability. The design integrates residential and communal spaces, promoting interaction while fostering a connection with the surrounding natural environment. The unique circular form of the structure represents unity and fluidity, while the use of local vegetation enhances the theme of cultural identity within the ecological framework.

Community-Centric Design

A central aspect of this project is its prioritization of communal living. The architectural layout features a central community area, functioning as a hub for social interaction. This space is complemented by flexible residential zones that maintain a balance between community engagement and personal privacy. The design allows for various activities, from workshops to gatherings, facilitating diverse functions.

The organically designed pathways enhance usability, guiding residents through the community seamlessly. These pathways encourage exploration while providing access to communal and private areas. The emphasis on connectivity within the project reflects a deep understanding of the role of social interaction in enhancing quality of life.

Material Selection and Environmental Integration

Careful consideration has been given to material choice, promoting sustainability and an ecological ethos. The use of hempcrete, known for its insulating properties, paired with a natural lime finish, contributes to the project's energy efficiency. These materials align with modern sustainable practices while providing a comfortable living environment.

Furthermore, the strategic incorporation of native flora, including fig trees and olive farms, both enhances the ecological footprint and anchors the project within its geographical context. The focus on natural materials and landscape integration underpins the design, allowing it to coexist harmoniously with the surrounding ecosystem.

In summary, "Spontaneous Home – The Community Home" exemplifies contemporary architectural practices that prioritize community interaction and environmental sustainability. The unique circular design, flexible communal spaces, and careful material selection distinguish this project from typical community housing developments. For additional insights into the architectural plans, designs, sections, and ideas that define this project, readers are encouraged to explore the full presentation.

`
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.
