The Spirala Community Home project features a residential design focused on community living and harmony with nature. The layout includes a spiral motif, which influences both the organization of spaces and the overall look of the home. Located in a natural setting, the architecture uses colors that reflect the surrounding landscape, creating a welcoming atmosphere for residents.

Spatial Layout

The design emphasizes accessibility and connection among residents. Curved ramps and pathways encourage movement throughout the building, while various seating arrangements promote socialization. A notable feature is the "reverse amphitheater," where exterior brick stairs extend into the hillside, allowing residents to gather and enjoy views of the sunset together.

Interior Organization

Inside the home, there are three main areas: the main hall, bathrooms, and kitchen. The main hall stands out with a Fibonacci spiral pattern on the floor, which draws attention and enhances navigation. The bathrooms are designed efficiently, with three compost toilets and one ADA-compliant stall to accommodate all residents. The floors display a Theodorus spiral design, adding a visual layer to functional spaces.

Materiality and Context

For the exterior, light-colored brick is combined with bright blue grout to create a visually appealing facade. This choice references the colors found in the blue city of Safed in Israel. Inside, Calcada Portuguese tiles in black, white, and off-white cover the flooring, providing durability alongside aesthetic appeal. A Tulikivi soapstone fireplace made in the Finnish style is positioned between the main hall and the gallery/WC, serving a practical need for warmth and addressing the local humidity.

Visual Details

The project pays close attention to small design elements. Hanging plants and native trees are integrated into the landscape, enhancing the natural feel around the home. The thoughtful design of indoor and outdoor spaces encourages interaction while promoting a sense of community. A glow-in-the-dark treatment on the spirals in the main hall adds a unique touch, reflecting the movement and activities of the residents, and creating an engaging atmosphere for all who enter.

`
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.
