High in the Rift Valley Mountains, the Dorze people have developed a technique of splitting and weaving bamboo. They use it ti make fences and baskets, coat it with clay to make storage pots, even make bee hives out of it, but most importantly, they make whole houses from it. Even the scaffolding and the ladders are made from bamboo.
Chesper houses are then thatched with wheat or barley straw, but the best are covered with...bamboo. There is a myth, propogated by local tour guides that they are covered with banana leaves, for a variety of banana is ideed grown locally. It does not friut but a bread can be made from the fermented pulp from the leaf ribs. Bit it is not durable enough to cover a house.
The houses are over seven metres high, and this allows for the gradual shrinkage as over the seventy years a typical house will last, it will lose around 2-5cm a year from rot, as the ground is quite wet.
Watch the video for full instructions on how to make your own, but you will need a good supply of thick bamboo.
