The Spirala Ecological Village is located in Portugal and emphasizes a strong connection to nature within a community-focused design. Inspired by the shapes of sea shells, the building reflects an architectural style that merges practicality with an appreciation for the environment. The community home serves as a gathering space where residents can engage in various activities while surrounded by an organic and inviting structure.

Design Concept

The core concept revolves around the spiral form, which is derived from the natural beauty of sea shells. This design not only offers aesthetic appeal but also facilitates unity with the surrounding landscape. The building’s shape and interior configurations encourage interaction among residents, creating an environment that promotes togetherness and shared experiences.

Materials and Sustainability

Rammed earth is used as the primary material for construction. It offers durability and excellent thermal properties. This choice underscores a commitment to sustainability, as rammed earth helps keep indoor temperatures steady throughout different seasons. The thick walls of the building provide insulation, helping to maintain comfort in both summer and winter while reducing the need for additional heating or cooling systems.

Passive Design Strategies

To enhance energy efficiency, the design incorporates various passive techniques. Sun shades are positioned according to the sun’s path in the sky, effectively managing how much sunlight enters the space. This design allows natural light to flood in while minimizing heat gain. The kitchen is centrally located to help distribute warmth generated from cooking, further contributing to a comfortable indoor climate.

Spatial Arrangements

The multifunctional hall is designed to be flexible, allowing for a variety of uses. Whether it’s a yoga class, dance session, or community meeting, the space can easily adapt to different activities. This versatility is key to encouraging engagement among residents. Open areas facilitate movement and collaboration, echoing the smooth lines of the building itself.

The detailed design of the shell structure adds a unique touch. Its curves invite exploration and create a welcoming atmosphere, blending indoor spaces with the natural landscape outside. Each element is thoughtfully considered to enhance the experience of community living while remaining sensitive to the surrounding environment.

`
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.
