Rammed Earth Walls and Layered Construction Celebrating Andean Heritage

Project in-detail

Constructed using rammed earth walls and a layered Pisè method, the design integrates traditional Andean heritage while providing a communal space that fosters connection to the natural environment.
5 key facts about this project
01
Rammed earth walls provide thermal mass and environmental stability.
02
The Pisè construction method incorporates local earth materials.
03
Design honors Pachamama, reflecting cultural and ecological values.
04
Layering technique symbolizes growth and regeneration in architecture.
05
Location-specific features connect occupants to the surrounding landscape.

The architectural design titled "Bringing Earth to the Earth" finds its roots in the cultural landscape of Ecuador, where respect for Pachamama, the Earth Goddess, shapes the underlying principles of the design. This work integrates sustainable building practices with a deep appreciation for the surrounding environment. It serves as a communal space that emphasizes heritage and the relationship between people and nature.

Design Concept
At the heart of the design is a commitment to Pachamama's ideals, where cycles of life and nature are key themes. The approach revolves around the Pisè construction technique, which employs plywood formwork to create walls made of rammed earth. The walls consist of layers of a moist earth mix, combining concrete, clay, gravel, and sand. This method not only supports environmental sustainability but also symbolizes concepts of growth and regeneration that are important in Andean culture.

Materiality
Rammed earth plays an essential role in expressing the project's values. Each layer of earth is compacted using a pneumatic backfill tamper, which enhances the structural strength of the walls. When the formwork is removed, the distinct textures of the soils emerge, showcasing the natural qualities of the materials. The finish reflects the surrounding landscape and provides good thermal performance, creating a comfortable indoor environment.

Cultural Context
The design draws on the rich heritage of Ecuador, referencing locations such as Achupalas, Timboyacu, Qullu Loma, and Ingapirca. These sites contribute to the broader narrative, reflecting a conversation about community and environmental responsibility. The project also aligns with Ecuador’s Constitution, which recognizes the rights of nature. This aspect strengthens the building's commitment to sustainability and encourages a respectful relationship between architecture and its environment.

Design Outcome
In its completed form, the building is not just a space for use; it embodies cultural values and an awareness of ecological balance. The rammed earth walls create a direct connection to the land, reflecting respect for nature. Natural light flows through the structure, enhancing the experience for occupants. The design invites people to engage meaningfully with the surrounding world, creating a space where culture, nature, and community intertwine.

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.
