A spiraling green skin crafted from bamboo envelops a multifunctional community space, fostering engagement and sustainability in a unique architectural expression.
5 key facts about this project
01
Spiraling "live" green skin enhances biodiversity and thermal performance.
02
Flexibility allows the pavilion to shift between insulated and open environments.
03
Community involvement is integral, with workshops for skill-sharing during construction.
04
Bamboo, a locally abundant material, serves as the primary structural element.
05
The design incorporates natural light through extensive skylights in the roof.

The "Living Spirals" project stands as a notable example of sustainable design, situated in the diverse landscape of Portugal. It focuses on creating spaces that foster community interaction while applying principles from circular economies and cradle-to-cradle philosophy. At its core, the Spirala Community Home features a circular layout, allowing flexibility in its use. This design is meant to support a variety of social activities, encouraging a sense of belonging among its users.

Design Approach

The approach taken emphasizes community participation at every stage. Local residents are invited to engage not only in the planning stages but also in the building process itself. Workshops are designed to help people learn skills that will enable them to contribute to construction and future upkeep. This involvement creates strong connections between the community and the space, fostering a collective responsibility toward the home.

Spatial Configuration

The main space within the Spirala Community Home is unique for its ability to transition between different forms. It can shift from a closed, insulated environment to an open, interactive pavilion. This change is made possible through sliding shutters, which adjust according to the climate and the needs of the people using the space. This versatility means the area can comfortably host various events, from workshops to casual meetings.

Green Integration

A significant feature of the design is the spiraling "live" green skin that wraps around the community space. This element not only improves insulation but also accommodates recreation and exhibition activities. Incorporating local plants reinforces a connection to the surrounding environment, promoting biodiversity. In addition, the green skin enhances the visual appeal, making the building a dynamic part of its setting.

Material Considerations

Sustainability plays an important role in material selection. Bamboo, known for its rapid growth and abundance in Portugal, is used in the construction. This choice not only reflects environmental responsibility but also supports local economies. Key elements like a light-weight roof with skylights allow for ample natural light, ensuring an energy-efficient design that aligns with the project's principles.

The "Living Spirals" project exemplifies a harmonious blend of nature, community, and thoughtful design. The spiraling green skin acts as a living feature, symbolizing the important relationship between built spaces and the natural world. This approach to architecture creates an inviting atmosphere that encourages interaction while remaining attuned to its environmental context.

`
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.
