05
Limestone calcinated clay cement significantly reduces carbon emissions in foundation work.
The Earth House is an architectural project situated in the Sahel region of Africa, focusing on sustainable living through the use of local materials and traditional construction techniques. This project addresses housing needs within the community while promoting environmental stewardship. The design incorporates efficient water management, energy production, and local community involvement, making it a significant response to the socio-environmental challenges in the area.

Sustainable Material Use and Construction Techniques

The Earth House employs stabilized rammed earth as its primary structural material. This choice not only provides necessary thermal mass and insulation but also utilizes locally available resources, enhancing the building's ecological footprint. The walls are designed with a thickness of 300 mm to optimize their performance. The project incorporates limestone calcinated clay cement (LC3) for the foundation and underfloor systems, considerably reducing carbon emissions traditionally associated with concrete construction. Roof elements utilize Kingspan QuadCore LEC insulated panels, which offer superior energy efficiency while maintaining structural integrity.

The project implements innovative water management through a rainwater harvesting system integrated with Kingspan rainwater tanks, ensuring a self-sufficient water supply. The landscape design includes circular pits for water conservation, improving soil fertility and promoting sustainable agricultural practices in the vicinity. Solar panels provide off-grid electricity, aligning energy production with the community’s needs.

Spatial Configuration and Community Engagement

The architectural layout of the Earth House offers a spiral configuration, promoting fluid movement through the space. This design facilitates both public and private areas, encouraging social interaction and community bonding. The integration of communal spaces is a critical element, recognizing the importance of collaboration and connection among residents.

Careful consideration has been given to the placement of apertures, allowing for ample natural light while preserving privacy. The building's orientation further enhances the connection between indoor spaces and the surrounding environment, making it a key aspect of the design. By utilizing local construction methods and resources, this project preserves cultural significance while fostering a sense of ownership among community members.

The Earth House stands as a model of architectural efficiency and sustainability. By prioritizing local materials, efficient energy solutions, and fostering community engagement, this project not only meets housing demands but does so in a manner that respects and enhances the local environment. For additional insights into the architectural designs, plans, and sections of the Earth House project, the presentation offers further details for those interested in exploring its innovative concepts and layout.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
