Reinterpreting Natural Building Materials

For generations, communities across Ghana and many parts of the world built their homes using natural, locally available materials such as clay, bamboo, wood, and plant fibers. These materials provided not only structural integrity but also embodied cultural heritage, environmental harmony, and traditional wisdom. However, with the rise of industrial construction methods often costly, resource-intensive, and environmentally unsustainable many of these indigenous practices have gradually faded.

The Reinterpreting Natural Building Materials (RENABUMA) Project seeks to bridge this gap by reimagining traditional building knowledge through the lens of modern technology. Led by TCC-CIMET in partnership with the Karlsruhe Institute of Technology (KIT), Germany, the project aims to design, prototype, and promote affordable, low-carbon, and high-quality housing solutions specifically tailored to Ghana’s urban context.

RENABUMA integrates renewable, bio-based local materials with advanced digital construction technologies such as computational design, digital fabrication, and material optimization to develop innovative building systems that are both culturally grounded and future-ready. Through this approach, the project contributes to several Sustainable Development Goals, including SDG 7 (Affordable and Clean Energy), SDG 8 (Decent Work and Economic Growth), SDG 9 (Industry, Innovation, and Infrastructure), SDG 11 (Sustainable Cities and Communities), SDG 12 (Responsible Consumption and Production), and SDG 13 (Climate Action).

At the core of RENABUMA is a commitment to circular construction, climate resilience, and local empowerment. The project envisions housing solutions that:

• Reduce carbon emissions by prioritizing renewable materials

• Leverage digital tools to enhance quality, efficiency, and scalability

• Celebrate local identity by integrating traditional knowledge into modern design

• Offer affordable and sustainable pathways for future urban development

To advance this vision, the project is hosting the RENABUMA Workshop, a collaborative platform that brings together academia, industry experts, and community stakeholders. The workshop is co-organized with support from the KNUST Centre for Settlement Studies, Department of Architecture, Department of Construction Technology and Management, College of Engineering, College of Science, the International Bamboo and Rattan Organization (INBAR), Mobius Architecture, SCiMLAB, and DDF–Professur Digital Design and Fabrication. Through hands-on activities, knowledge exchange, and prototype development, participants will explore innovative, climate-responsive, and locally appropriate construction approaches.

Ultimately, RENABUMA is more than a technological project it is a transformative effort to rethink how we build. By blending the ingenuity of traditional materials with the power of digital innovation, RENABUMA aims to create sustainable housing solutions that honor heritage, reduce environmental impact, and empower communities for generations to come.
