Emphasizing Decay Through Rammed Earth and Natural Elements

Project in-detail

A temporary rammed earth wall, designed to gradually decay over time, invites visitors to explore the pavilion’s intimate connection with its natural surroundings while offering a unique exhibition space focused on the life cycle of materials.
5 key facts about this project
01
Rammed earth construction highlights material's natural lifecycle.
02
Cave-like entrance creates an intimate visitor experience.
03
Rainwater flows through central openings, enhancing acoustic qualities.
04
Temporary wall designed for gradual decay reflects ephemerality.
05
Located at the intersection of lake and mountain, promoting environmental engagement.

The design in Weissenssee, Austria, is a pavilion made of rammed earth, located at the meeting point of the lake and the mountain. It explores the life cycle of this material, inviting visitors to experience its journey from rough texture to refined form and then to purposeful decay. The structure reflects on the nature of architecture, encouraging a dialogue between the built environment and the natural world.

Entrance Experience

The entrance has a solid, monolithic shape that leads into a narrow, cave-like space. This creates an intimate setting, contrasting with the bright, open area that follows. A window placed strategically in the corner frames the view of the mountains outside, allowing natural light to filter in and connect the interior with the landscape.

Water Management Integration

Rainwater flows through the pavilion without interference, falling through a central opening in both the roof and floor. This feature not only adds an auditory element to the design but also strengthens the link between the building and its surroundings. The sound of the water creates an immersive atmosphere, enhancing the overall experience as visitors move through the space.

Decay and Ephemerality

As people navigate toward a West-facing opening that leads to a pier, they notice signs of decay. A temporary wall made from rammed earth is intended to slowly vanish over time, representing the fleeting nature of materials. The roof is designed to guide rainwater onto this wall, encouraging gradual deterioration, which ties back to the central theme of the pavilion's life cycle.

Material Palette

Local materials such as rammed earth, stone, and timber are used throughout the design. This choice not only supports sustainability but also ensures that the pavilion relates well to its environment. The textures and colors of these materials create a harmonious connection between the building and its natural setting, allowing for a deeper interaction with the surroundings.

Inside, the pavilion offers carefully considered spaces where light and shade play across the surfaces. This thoughtful arrangement invites users to engage closely with their environment, providing a rich and meaningful experience.

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.
