Questions & Answers

Q: How does mud construction in African architecture coexist with nature?

Mud construction in African architecture harmoniously blends with nature due to its use of locally available materials, such as branches and mud, creating strong walls and thatched roofs that provide protection from the sun and absorb/release heat.

Q: How does the use of thatched roofs contribute to sustainability?

Thatched roofs, made from locally sourced materials and reinforced with bamboo, offer homes natural insulation, protection from extreme weather events, and a reduction in carbon emissions compared to energy-intensive iron sheets.

Q: Why is it important to shift perspectives on African construction?

Shifting perspectives on African construction is crucial due to the damaging environmental impact of cement production and the ineffectiveness of cement in cooling homes. Utilizing locally available materials like mud can create sustainable homes while reducing carbon emissions.

Q: What is the biggest obstacle to the shift back to mud construction?

The biggest obstacle to shifting back to mud construction is the mindset and perception that cement is superior. However, it is as simple as mixing clay with cement to create sustainable bricks, highlighting the need for a change in mindset.
