CSEB Construction with 3D-Printed Roof and Efficient Rainwater Harvesting in a Sustainable Microhome

Project in-detail

Utilizing compressed stabilized earth blocks and a 3D-printed roof, this design promotes efficient rainwater harvesting and community engagement through its self-sufficient microhome that addresses essential housing needs.
5 key facts about this project
01
Utilizes compressed stabilized earth blocks for efficient thermal regulation.
02
Features a 3D-printed roof that supports rainwater collection.
03
Incorporates an incinerating toilet to enhance sanitation without plumbing requirements.
04
Engages local communities in the construction process to foster ownership.
05
Designed with a flexible layout to adapt to various family needs.
The Core is an architectural project designed to address essential housing needs in southern Burkina Faso. This microhome serves as a prototype for sustainable living, especially for those lacking access to vital resources such as electricity, clean water, and sanitation. The project embodies a commitment to environmental and social sustainability while providing a functional living space tailored for low-income communities.

Functional Design and Layout
The design of The Core optimizes living space through a compact and efficient layout. It includes essential functions such as a sleeping area, kitchen, work space, and sanitation facilities, all within an open-plan configuration that promotes flexibility and interaction among residents. Large openings and strategically positioned windows ensure adequate natural light and ventilation, enhancing comfort in a hot climate while reducing reliance on mechanical cooling systems.

Local Materiality and Sustainability
One of the project’s distinguishing features is its focus on local material use and sustainable practices. The primary building material is Compressed Stabilized Earth Blocks (CSEB), which not only provides thermal regulation but also supports local economies through community-based production. The 3D-printed roof structure adds another layer of innovation, facilitating rainwater collection while providing necessary shade. Eucalyptus wood enhances the interior, combining aesthetic value with durability.

The project integrates advanced technological solutions such as solar panels for renewable energy generation and an innovative incinerating toilet that enhances sanitation without traditional sewage systems. Water management is prioritized through rainwater harvesting and filtration systems, ensuring a consistent supply of clean water.

Unique Design Approaches
The Core represents a community-centric approach to design, engaging local residents in the construction process. This involvement fosters ownership and connection to the project, essential for its long-term success in impoverished areas. Additionally, the design emphasizes cultural relevance by incorporating local building techniques and practices, ensuring acceptance by the community.

Scalability is another important aspect; the architectural solutions are adaptable, making them applicable in various geographical contexts facing similar housing challenges. This focus on resource efficiency not only minimizes environmental impact but also aims to improve residents' overall resilience.

For a comprehensive understanding of The Core’s architectural plans, sections, and design ideas, readers are encouraged to explore the project presentation. The details provide insights into the unique architectural strategies employed and their potential applications in similar contexts.

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.
