[snip] Unlike the prior periods of the Stone Age, people in the Neolithic Age mostly lived in settled societies. Because of this, they no longer lived in impermanent structures like huts and caves, but, for the most part, actually built homes. Homes were usually built around a central hearth, or stone or brick fireplace, which was used to warm the house and to cook. At the beginning of the period, homes were usually one room, but towards the end, they were often multi-roomed, sometimes even having two stories. These homes, often called long houses, were usually rectangular, no matter how many rooms they had. Homes were made primarily of mud brick, which was simply mud formed into bricks and dried. While mud brick was not as sturdy or permanent as other materials, it was cheap and easy to make since mud was easy to find. Mud brick homes sometimes had wood frames depending on the location, but were mostly made from mud brick with just one door and no windows. [/snip]
