A temporary rammed earth wall designed to erode over time contrasts with expansive spaces filled with natural light, creating a reflective environment that invites contemplation by the lake.
5 key facts about this project
01
Rammed earth walls are designed to naturally deteriorate, illustrating impermanence.
02
A monolithic entrance creates a cave-like atmosphere that enhances introspection.
03
Natural light enters through a corner window, framing views of the mountain landscape.
04
Rainwater is channeled onto a temporary wall, actively contributing to its decay.
05
Locally sourced materials reinforce the structure’s connection to its environment.

The rammed earth pavilion is located in Weissenssee, Austria, positioned between a serene lake and striking mountains. It serves as a space for reflection while exploring the life cycle of rammed earth as a building material. The design concept reflects the journey of this material, showcasing its transformation from raw form to refined structure, and eventually to decay. Visitors experience this narrative through a thoughtfully planned sequence of spaces.

Design Intent

Occupants are guided through three distinct areas, each designed to evoke specific feelings. The entrance presents a dense, solid façade that draws people in. As visitors enter, they find themselves in a narrow, cave-like environment. This initial experience creates a sense of curiosity and prepares individuals for the journey ahead.

Spatial Experience

After passing through the entrance, visitors reach a central space filled with light. Sunlight pours in, brightening the area from a carefully positioned window that frames views of the surrounding mountains. This openness creates a connection between the interior and the landscape outside, making visitors feel both refreshed and uplifted.

Decay and Impermanence

As people move toward the west-facing opening that leads to the pier, the theme of decay becomes apparent. A temporary rammed earth wall is present in this section, specifically designed to erode over time. Rainwater from the roof is directed onto this wall, promoting its gradual breakdown. This feature prompts reflection on the fleeting nature of materials and life itself.

Material Considerations

The pavilion incorporates locally sourced materials such as earth, stone, and timber. These choices reinforce the connection to the site and enhance the overall aesthetic. The focus on sustainable practices and the historical significance of rammed earth enrich the overall experience, making it relevant to modern architectural discussions.

Observing the pavilion, one notices how light and shadow dance across the textured surface of the rammed earth walls. This creates a visual experience that changes throughout the day. The building's exterior interacts with the landscape, highlighting the relationship between the constructed space and its natural surroundings.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
