House
Another way to make a house of mud or clay is to shape the wet soil into bricks before building the walls. The bricks can be shaped by hand, but more often they are shaped in boxes or "moulds" so that all the bricks are just the same size and shape. They are left in the hot sun until they have dried hard. Then walls can be made which are the same thickness all the way up. Clay bricks that are dried in the sun were used in Egypt and Mesopotamia for thousands of years.
