A new two-story house design for sub-Saharan Africa is cheaper to build, and releases less carbon, than conventional construction. A randomized controlled trial found that it was associated with lower childhood disease: 44% lower for malaria, 30% for diarrhea, and 18% for respiratory infections.

These unusual two-story homes are rewriting child survival in rural Africa in ways few expected
A major study involving Durham University shows that a radical rethink of rural housing design in sub-Saharan Africa can protect children from the three deadliest childhood diseases. The three-year trial in Tanzania found that children living in specially designed two-story "Star Homes" had dramatically lower rates of malaria, diarrhea, and acute respiratory infections compared with children in traditional mud-and-thatch houses. The children in the Star Homes also grew taller as a result of their better health. The research is published in the journal Nature Medicine.
