Mohenjo-daro had a planned layout with rectilinear buildings arranged on a grid plan. Most were built of fired and mortared brick; some incorporated sun-dried mud-brick and wooden superstructures. Sites were often raised, or built on man made hills.
so in my unit my hous is made out of bricks, all the other neccesities and they also were different because it is made out of stone and mine isnt,
my home has a roof while they were exposed to all the weather?
i hope this helps <3
