5 key facts about this project
01
Community center designed around the concept of spirulina to reflect harmony with nature.
02
Thermal comfort achieved through 40 cm thick concrete walls that insulate against heat.
03
Kitchen wall constructed with traditional rough stone masonry for cultural connection.

The Spirala Community Home is located in central Portugal, a region marked by hot, dry summers and cool winters. The design draws on the natural landscape, aiming to connect the building with its environment. Inspired by spirulina, the project symbolizes ongoing movement and balance, reflecting the community's desire for a sustainable lifestyle closely linked to nature.

Community Integration

The layout of Spirala is designed to encourage connection among residents. Essential spaces, including the assembly area, kitchen, event hall, and outdoor and semi-outdoor plazas, are organized to promote social interaction. This design blueprint allows for various community activities while reinforcing a sense of togetherness among residents.

Thermal Performance

A critical aspect of the design is its attention to thermal comfort. The building features a 40 cm thick concrete wall, which helps to block external heat during the hot summer months, ensuring a comfortable indoor climate throughout the year. This approach to regulating temperature highlights a focus on energy efficiency and livability.

Cultural Context

The project reflects local traditions by incorporating a kitchen wall made of rough stone masonry. This choice connects the structure to the region’s architectural history. By using locally inspired materials, the design bridges contemporary needs with cultural heritage, adding depth to its overall character.

Natural Lighting

Natural light is a key consideration in the design through the inclusion of a large glass wall facing south. This element invites plenty of daylight into the building and is paired with deep shading features that control brightness levels. The thoughtful use of light enhances the interior atmosphere, creating spaces that feel both open and inviting.

The expansive glass not only illuminates the interiors but also frames views of the landscape, merging indoor and outdoor experiences. This connection to nature is integral to everyday life in the community.

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.
