These are precisely the construction techniques used in Mayotte for traditional homes (not so much nowadays anymore). Roughly half the population immigrated from east Africa so not exactly surprising, but worth noting.

Traditionally, when growing up (teenage years) boys leave the family home and build themselves a banga, which is a small home made of a wooden frame (bamboo I think) covered in clay just like in the picture. My understanding is this is how teenagers first learn to live on their own. Upon marriage, they go live in their spouse’s home, which -I think- is built by her family.
