Yeah you're absolutely right, a lot of countries in Africa still bodge together makeshift building blocks out of dried animal dung! But that's in Africa, not among the oil rich Arab states of the middle east, which is where Jordan is. Different continent, and even though Jordan isn't the richest country in the area i'm sure, with their wealth of gas and oil reserves, that they have sufficient building products to build structurally sound houses with and even something lying about to put a tiny little fish tank on.
