The Rammed Arcth is an architectural proposal located in Merapi, Indonesia, designed to explore new possibilities within rammed earth construction. The pavilion serves as a place for visitors to rest while enjoying views of the Merapi volcano. The design emphasizes gravity-defying forms and a connection to the geological processes that have shaped the landscape, offering a rich narrative tied to the earth's mineral heritage.

Design Concept

The idea behind the pavilion focuses on the extraction of earth as both a functional element and a central theme of the structure. It features three curved masses that interlace to create a self-supporting canopy. This arrangement defines spaces within and around the pavilion, promoting gathering and contemplation in a dynamic setting. The overall form invites a conversation between the natural and built environments.

Materiality

Local volcanic soil acts as the primary material for constructing the pavilion. This choice strengthens the connection to the surrounding landscape and enhances the visual and tactile experience. The dark attributes of the volcanic material reinforce the building's roots in its geological environment, allowing it to resonate with the natural surroundings more deeply.

Spatial Interaction

Visitors are encouraged to engage with the structure and its spaces on multiple levels. The design includes curved forms that are deliberately tilted, framing specific views of the Merapi volcano. These design decisions create a visual dialogue between the pavilion and its surroundings. The thoughtful arrangements of paths and viewpoints allow for exploration and varied experiences for those who enter the space.

As people move through the pavilion, they find a blend of nature and architecture. The rammed earth patterns and flowing forms create an inviting atmosphere that encourages reflection and a deeper appreciation for the landscape’s history and beauty.

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.
