5 key facts about this project
01
Rammed earth construction reflects local building traditions and environmental respect.
02
Circular design elements symbolize the cultural significance of Pachamama.
03
Sustainable materials sourced from the surrounding area minimize environmental impact.
04

"Bringing Earth to the Earth" is located in Ecuador at the Ingapirca Ruins, an area rich in Andean culture and history. The design focuses on the relationship between the built environment and nature, drawing inspiration from Pachamama, the Earth Goddess. This connection shapes the concept of honoring the land while integrating traditional building methods that resonate with local heritage.

Construction Technique

The construction method used is Pisè, a technique that focuses on sustainability through rammed earth. The process involves plywood formwork filled with a mixture of concrete, clay, gravel, and sand. Initially, a layer of moist earth is compacted using a tool called a pneumatic backfill tamper. After achieving the desired compactness, additional layers are added one by one. As the process continues, the wall gains strength and height until it reaches completion.

Cultural Context

The design incorporates circular forms that symbolize Pachamama. This connection reinforces cultural identity and speaks to the importance of nature. The circular elements are both functional and meaningful, inviting reflections on how humanity relates to the earth. These forms serve as a reminder of the beliefs held by the Andean peoples, capturing the philosophy of balance between people and nature.

Sustainability and Legal Framework

The project aligns with the environmental principles found in Article 71 of the Ecuadorian Constitution, which emphasizes the rights of nature. This legal framework influences the design by encouraging respect for ecological integrity. By using locally sourced materials and sustainable practices, the project acknowledges its responsibility to the environment and encourages others to do the same.

Design Aesthetics

The rammed earth walls do more than provide structure. Their textures and colors connect with the natural landscape. The materials used create a warm, inviting presence, drawing people to interact with the space. The design emphasizes the relationship between human-made elements and the environment, fostering a greater appreciation for both.

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.
