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.

Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025.
