Building A Mud House

One of the best places I visited in Zambia was the village of Siankaba on the Zambezi River. While there, I got to know “Doctor,” a guide who proudly showed me the new home he was building. Many of the details he explained found their way into my novel, Heart of Diamonds.

In Siankaba, just as where I live in New York, no project begins without a building permit issued by the appropriate authorities. Before Doctor could build his new home, he had to get permission from the village headman since all land belongs to the village. Doctor’s old house, by the way, won’t be sold. It will belong to the next person who needs a home as adjudged by the headman.

Once the site is approved, it is cleared and leveled, then holes where the walls will be are dug about a foot deep and two feet apart. They will hold upright studs of straight mopane logs about four inches thick and perhaps eight feet long. They’re held in the foundation holes with tamped earth, not cement.

Headers of similar size longs are lashed to the top of the studs. Thin sticks and reeds are woven through the studs, with holes left for doors and windows. Along with the headers, they provide stiffness to the framework. They also serve as lath to hold the mud which comes next.

The mud is more than just dirt and water. It’s mixed with soil from the gigantic termite mounds that dot the countryside—earth that has passed through the insect’s digestive tract. It contains a hardening agent that enables the mounds to withstand rains and attacks by predators for a hundred years or more. The walls of a well-built hut will be as hard and durable as concrete once they dry in the hot equatorial sun.

Mopane joists are lashed to the wall frame and a roof is laid on top. It may be tin, which lasts 20+ years, or thatch, which is good for seven but costs considerably less. Depending on the financial health of the builder, doors and windows may be nothing more than cloth or canvas draped over the openings or prefab manufactured items with glass and locks.
