Those who live in Mud Houses.
Kristen Kieffer shared this link about these fascinating houses. I love them because the are in line with the bridges made of snow project that I just had my Freshman students do. there is something wonderful about working with limitations. The way that function and basic materials force us into making decisions with limited scope but infinite potential.
The Mugsum people in northern Cameroon are known for thier clay houses. Gigantic in scale and heavily decorated, these houses function as housing, but also provide circulation and cooling.
