Ribbed Earthen Shell Houses

Ribbed Earthen Shell Houses is an original illustration set in Pouss, Far North Cameroon. It lies in the tropics, where the climate is hot semi-arid steppe.

Several tall oval earthen houses taper to small round vents above a sandy compound near the Logone floodplain. Strong raised ribs curve from ground to apex, small shaded doorways face an inner yard, and fresh rain channels mark the ochre surface while millet stalks and a few acacias stand nearby.

Why do these earthen houses rise as tall ribbed shells?

A continuous tapered earth shell encloses useful volume with little timber, and its thick mass delays the transfer of fierce daytime heat. Raised exterior ribs stiffen the form, shed wet-season rain, and provide footholds for repeated plaster maintenance; the tiny high vent releases smoke and hot air without opening a broad sun-facing window. Those linked responses to heat, scarce wood, and seasonal storms identify Musgum architecture on the Logone plain.
