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.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
