The Spirala ecovillage is situated in the rolling hills of eastern Portugal, characterized by a landscape of granite boulders, fig trees, pines, and cork oak trees. The community home, named the Zome, serves as a central place for gathering and communal activities. Its design concept focuses on geometric shapes that connect with nature, fostering a sense of community and encouraging sustainable living.

Design Concept

The Zome features a unique geometric structure made up of diamond-shaped panels arranged in a double spiral. This design not only creates visual interest but also echoes the natural forms found in the surroundings. Positioned at the highest point on the site, the building captures sweeping views of the distant countryside, establishing a strong link between the structure and its environment.

Spatial Arrangement

The interior space of the Zome encompasses 226 square meters, providing an open layout free of columns. This allows for flexibility in how the space is used. The main multipurpose room is separated from a service area by an arched partition, creating a balance between privacy and openness. The room's acoustics are well-suited for various activities, such as gatherings and meditation, reflecting the communal spirit intended by the design.

Access and Interaction

Five large entrance doors facilitate access to the Zome from different sides. This thoughtful layout encourages movement and interaction among visitors and residents. Large glass doors and windows, along with a skylight, allow natural light to fill the interior, making the space bright and inviting. This design choice helps to create a connection between the indoor environment and the outdoors.

Functional Elements

On the eastern side, the design includes essential services such as three dry toilet cabins and a functional kitchen, which are discreetly positioned behind a partition. This arrangement provides direct access to outdoor terraces. These terraces serve as additional gathering spaces, promoting social interaction while respecting the natural features of the site.

The Zome's architecture works in harmony with its surroundings, creating a welcoming space that encourages community and interaction. It reflects a thoughtful approach to design where the building and its landscape enhance the overall experience of communal living.

`
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.
