Inspired by the organic movement of lava, the museum's curvilinear forms and semi-permeable surfaces create a harmonious relationship with the landscape while providing a versatile space for art exhibitions.
5 key facts about this project
01
Curvilinear forms reflect the natural movement of lava.
02
Flexible exhibit walls allow for diverse art arrangements.
03
Semi-permeable surfaces minimize water run-off.
04
Green roofs enhance insulation and support biodiversity.
05
Strategically placed glass surfaces optimize daylight in galleries.

TerrAstral introduces a design that connects earth and sky in a unique way. Set in a landscape that highlights natural elements, the building serves as a museum, showcasing art while embodying the movements of nature. The architecture features flowing forms that resemble the motion of lava, creating a connection between the constructed space and its natural surroundings.

Conceptual Foundations
-
The design carries a dual theme that changes from day to night. By day, it reflects the undulating shapes found in volcanic landscapes, while at night, illuminated lines mimic the soft glow of the Aurora Borealis. This approach establishes a conversation between architecture and the environment, resulting in a space that shifts in appearance and feel throughout the day.

Sustainable Design Strategies
-
Ground surfaces are intentionally designed to be semi-permeable or permeable. This allows water to be absorbed naturally, reducing rainwater run-off. Such considerations enhance environmental responsibility and help integrate the building with its landscape. Additionally, the green roofs contribute to insulation and support local wildlife, fostering a sense of ecological balance.

Spatial Configuration and Flexibility
-
The building’s orientation maximizes daylight while minimizing unwanted heat. Glass surfaces are used to allow light from the north, protecting exhibits from harsh sunlight. The exhibition areas include movable walls that can be rearranged as needed, allowing for different layouts based on the art being showcased.

Visitor Engagement and Experience
-
Distinct public and private spaces enhance the visitor experience. A café provides both indoor and outdoor seating, encouraging people to engage with their natural surroundings. The thoughtful layout supports a connection to nature, while sustainable features highlight the building's commitment to reducing its ecological impact.


The final design element is the ground surface, which gently rises and falls, creating a natural flow between the building and the landscape. This approach resonates with the overall theme of harmony between the structure and its 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.
