In Mali, most dwellings are constructed this way. This is their architecture..just like how we have 'Victorian', Greek Revival.., Roman.. Etc. They use what wood they have and then clay. They have to coat these buildings with fresh layers of clay almost every year I believe. There was a really good TV show on some cable of public access channel about a year ago about Djenne.
Plus like they say...Beauty is in the eye of the beholder. One mans art is another man's..... I dunno..but something not art
Personally, I think it's quite lovely as well.
